When and How to Discount Your Products
Before You Discount
The most important question before running any promotion is: what specific business problem does this discount solve? Valid reasons to discount include clearing excess or aging inventory before it generates additional storage fees, acquiring new customers who will return for full-price purchases, boosting sales velocity to improve marketplace ranking, increasing average order value through tiered or bundle discounts, and competing during peak promotional periods like Black Friday when customers expect deals. If your reason is "sales are slow and I want to sell more," that is not specific enough. Ask why sales are slow and whether a discount is the right solution or whether the problem is visibility, conversion, or product-market fit.
Step-by-Step Discount Planning
Write down exactly what the discount needs to accomplish in measurable terms. "Clear 500 units of winter inventory by March 1 to avoid $1,200 in monthly storage fees." "Acquire 200 new email subscribers through a first-purchase discount to build our email list for Q4 campaigns." "Increase average order value from $38 to $48 through a tiered discount that rewards larger orders." The goal determines the discount structure, the target audience, the discount depth, and how you measure success.
Every discount reduces your per-unit margin, so you need to sell more units to generate the same total profit. The breakeven formula is: Breakeven Volume Increase = Discount % / (Current Margin % - Discount %). If your product has a 50% margin and you offer a 20% discount, you need: 20% / (50% - 20%) = 67% more units to break even. That means if you normally sell 100 units per week, you need to sell 167 units during the promotion just to earn the same profit as a normal week. If the 20% discount only increases volume by 30%, you have lost money compared to selling at full price. Run this calculation before every promotion, and be honest about whether the expected volume increase is realistic.
Different structures achieve different goals. Percentage off (15% off, 25% off) is the most common and works for broad promotions. Dollar amount off ($10 off orders over $50) works better for increasing average order value because the minimum threshold encourages customers to add items. Buy-one-get-one (BOGO) doubles the quantity sold and works well for consumable products where the second unit will be used rather than returned. Tiered discounts (10% off $50+, 15% off $75+, 20% off $100+) progressively reward larger orders. Bundle discounts offer a reduced price when products are purchased together, increasing units per transaction. Choose the structure that aligns with your goal from step 1.
Open-ended discounts are the most dangerous because they train customers to always wait for a sale and they give discounts to customers who would have bought at full price. Time limits (48-hour flash sale, this weekend only) create urgency and prevent indefinite margin erosion. Minimum purchase requirements ($10 off orders over $75) ensure the discount drives higher order values, not just lower prices. New customer restrictions (first order only) prevent existing customers from getting discounts on purchases they would have made anyway. Quantity limits (limit 2 per customer) prevent resellers from buying your discounted inventory in bulk.
After the promotion ends, compare the results to your goal from step 1 and to the breakeven calculation from step 2. Did you sell enough additional units to beat the breakeven threshold? Did total profit during the promotion exceed what you would have earned at full price? For customer acquisition goals, did the new customers acquired through the discount return for a second purchase at full price within 60 to 90 days? If a discount drives 500 new customers but none of them return, the acquisition cost per retained customer is the entire discount value, which is almost always too expensive. Track these metrics consistently to build an understanding of which promotions actually generate positive ROI for your business.
Discount Types That Protect Margins
Tiered Discounts
Tiered discounts give customers increasing incentives to spend more: 10% off orders over $50, 15% off orders over $100, 20% off orders over $150. This structure works because it increases average order value rather than simply reducing the price of what customers were already planning to buy. A customer who intended to buy a $45 item has an incentive to add a $10 accessory to reach the $50 threshold for 10% off. A customer with a $90 cart has an incentive to add another $15 item to reach $100 for 15% off. The additional items purchased at the higher tiers often have enough margin to offset the increased discount percentage.
Conditional Free Shipping
Offering free shipping above a minimum order value is technically a discount (you are absorbing the shipping cost), but it feels like a bonus to the customer rather than a markdown on your products. "Free shipping on orders over $49" encourages customers to add items to reach the threshold, increasing average order value without reducing the perceived value of any individual product. The threshold should be set 20% to 30% above your current average order value so that a meaningful percentage of customers increase their order to qualify. If your average order is $38, a $49 free shipping threshold gives many customers a reason to add one more item.
Bundle Discounts
Selling products together at a combined price lower than the individual prices creates perceived savings while increasing your total revenue per transaction. A three-product bundle at $59.99 ("save $15 versus buying separately") costs the customer $15 less but generates $59.99 in revenue from a single transaction instead of perhaps $24.99 from the single product the customer originally intended to buy. The customer buys more than planned, you sell more units, and the "discount" is more than offset by the increased transaction size. Bundle discounts work best when the products are genuinely complementary: a yoga mat bundled with a strap and cleaning spray, a skincare routine set, or a kitchen knife with a sharpening steel and cutting board.
When to Avoid Discounting
Do not discount simply because sales are slow unless you have ruled out other explanations. If your conversion rate is low, the problem might be your listing quality, photos, or reviews rather than your price. If your traffic is low, the problem is visibility and marketing, not pricing. A discount on a product that nobody can find does not solve the underlying problem; it just reduces your margin on whatever organic traffic you do get.
Do not discount products that are selling well at full price. This seems obvious, but many sellers include their best sellers in sitewide promotions "because they drive traffic." Your best sellers are best sellers because customers value them at the current price. Discounting them gives away margin without gaining anything you did not already have. Instead, use best sellers as anchors at full price and discount slower-moving or seasonal products that need the volume boost.
Be very cautious about training customers to wait for discounts. If you run a 20% off promotion every month, your regular customers will stop buying at full price and wait for the next sale. Brands like J. Crew and Bed Bath & Beyond became so dependent on constant promotions that their full prices lost all credibility with customers. The solution is to keep promotions infrequent and unpredictable so customers cannot plan around them, or to use discount structures that are only available to specific segments (new customers, email subscribers, loyalty members) rather than being publicly and repeatedly available to everyone.
Holiday and Seasonal Promotions
Black Friday, Cyber Monday, Prime Day, and other major shopping events create customer expectations for discounts. During these periods, competing at full price is difficult because customers are actively deal-hunting and marketplaces prominently feature discounted products. The strategic approach is to plan your promotional calendar in advance, budget for the margin reduction, and structure your deals to maximize customer acquisition and order value rather than simply cutting prices across the board.
For Black Friday and Cyber Monday, many successful sellers discount a few high-visibility products aggressively to drive traffic and offer smaller discounts or bundle deals on the rest of their catalog. The heavily discounted products serve as traffic magnets, and the customers who arrive for the deal often browse and purchase additional items at or near full price. This is the loss leader strategy applied to promotional events.
Track the full-year impact of your promotional calendar, not just the results during each individual promotion. If your annual revenue is $500,000 and you ran promotions that generated $80,000 in discounted sales but reduced margin by $25,000, the net impact depends on how much of that $80,000 was incremental (from new customers or increased volume) versus cannibalized (from existing customers who delayed purchases to wait for the sale). Many sellers discover that their promotional activity generates less incremental profit than they assumed because a significant portion of promotional revenue would have occurred at full price without the discount.
