Install DealCraft — It's FreeEach discount type has different profit implications. Use this guide to pick the best strategy for your goals.
Best for store-wide sales and seasonal promotions. Easy for customers to understand. Works well on high-margin products (50%+ margin) where you can afford 15-25% off.
Best for high-ticket items where a percentage would be too large. "$10 off" feels more concrete than "5% off" on a $200 product. Use for minimum order thresholds.
Equivalent to 50% off per unit. Best for clearing inventory or increasing average order value. Works best on low-cost items where you still profit at half price.
Encourages bulk purchases. "Buy 3 Get 1 Free" = 25% effective discount but moves 4 units instead of 1. Best for consumables and repeat-purchase products.
It depends on your product margins and goals. Percentage off works best for high-margin products. BOGO is great for clearing inventory. Volume discounts (Buy X Get Y) maximize units sold. Use the calculator above to compare exact profit margins for your specific product price and cost.
BOGO (Buy One Get One) is equivalent to 50% off per unit. If you sell a product for $50 with a $20 cost, BOGO gives you $25 revenue per unit (customer pays $50 for 2 units). Your profit is $5 per unit, or 20% margin. Enter your numbers in the calculator above to see your exact BOGO profitability.
Both give the customer a 25% effective discount, but they behave differently. "25% off" applies to every unit. "Buy 3 Get 1 Free" requires the customer to purchase 4 units to get the discount. This increases your average order value and moves more inventory. For a $50 product with $20 cost, both give you $37.50 effective price per unit, but "Buy 3 Get 1" sells 4 units per transaction instead of 1.
Shopify's native discount system supports basic percentage and fixed amount discounts. For advanced discount types like BOGO, Buy X Get Y, volume discounts, and automatic discounts, you need a discount app. DealCraft supports all discount types with cart-level calculation powered by Shopify Functions.
