Can I test discount vs free shipping offers?

I'm running an e-commerce store and want to understand which promotional strategy drives more conversions: percentage discounts or free shipping offers. I've noticed customers seem to respond differently to these promotions, but I lack concrete data on their comparative effectiveness. I need a systematic approach to testing these strategies, understanding their impact on average order value, conversion rates, and overall revenue. What methods can I use to scientifically compare discount and free shipping offers?

TL;DR - Quick Answer

Test discount vs. free shipping offers in Growth Suite by running two campaign variants to the same audience segment: one offering a percentage or fixed discount, the other offering free shipping. For most stores, free shipping converts as well as a 10-15% discount while having lower margin impact on high-margin products.

Testing Discount vs. Free Shipping Offers

Free shipping and discount offers serve the same psychological function (reducing perceived cost) but have different margin implications. Testing determines which resonates more with your customers.

When free shipping wins: On orders over $75-100, free shipping typically costs less than an equivalent 15% discount (e.g., $8 vs. $15 on a $100 order) while converting at a similar rate. For low-value orders, a percentage discount may feel more significant.
