Free Gift & Gift-with-Purchase A/B Tests: 7 Results

All 7 measured free gift tests in this collection won, but one of those wins came from removing a gift.

The most useful pattern: a gift that fits what the buyer is about to do worked, and a gift worth less to shoppers than a lower price did not.

Oliver Kenyon's free BBQ recipe e-book with knife purchases lifted revenue per visitor +48.71%.

Oliver also lowered a price to $82 and removed the gift (against $85 plus gift) for +46% conversion rate.

What counts as a free gift

This collection covers gifts with purchase, digital freebies, mystery gifts unlocked at a cart threshold, and tiered spend rewards.

It also includes a paid gift wrapping upsell, which is gift-related but not free.

The win/loss record

7 wins, 0 losses. Five of the seven are Oliver Kenyon's, and two of those describe a BBQ recipe e-book with similar wording, so they may be related.

Treat the record as a set of ideas, not proof gifts always help.

Biggest wins and their numbers

A gift that matches the purchase

Oliver Kenyon's client selling cooking knives added a free BBQ and grilling e-book, delivered by email after purchase.

Revenue per visitor rose +48.71%. Oliver puts it down to fit: people buying knives before summer are already picturing cooking outdoors.

A separate Oliver post reports a free Summer BBQ e-book added to product bundles: +$68,000/month and +$0.74 revenue per session.

Gifts as cart rewards

Oliver's tiered spend rewards in the cart (free shipping plus bonus items) reported +$57k/month and +$7.86 revenue per session.

Kasper Dolk's second-threshold mystery gift in the cart gave a +€30,578 revenue lift at 99% confidence over 9,868 visitors.

Milos tested a leather strap against a mystery box as the cart drawer upsell for a watch brand: +15.26% revenue per visitor and +18.19% conversion rate, with AOV down 2.48%.

The post doesn't say which option was the variant.

Gift wrapping

Oliver moved a gift wrapping option into the cart with a "Buying for someone else?" prompt and reported +$58,860/month.

It had lost before; survey data showed customers wanted gift wrap but couldn't find it.

When removing the gift won

Oliver tested $82 with no gift against $85 plus a gift.

The lower price won with +46% conversion rate and +$43k/month.

Oliver's read: these shoppers cared more about price than the bonus.

It's the closest thing to a losing gift test here.

How to add free gifts on Shopify

Automatic gifts at a spend threshold usually need a gift-with-purchase or cart rewards app, or Shopify's automatic discounts.

Digital gifts like e-books can be sent in the order confirmation email or a post-purchase flow.

How to test it on your store

  • Hypothesis: a gift tied to how the product gets used will raise revenue per visitor more than a generic discount.
  • Metric: revenue per visitor and profit per visitor, since gifts cost margin.
  • Control to include: if you can, test the gift against a lower price, as Oliver did.

Questions

Do free gifts with purchase increase conversions?

All 7 measured tests here won. Oliver Kenyon's free BBQ e-book with knife purchases lifted revenue per visitor 48.71%.

But Oliver also found a $3 lower price beat the same product with a free gift.

Does a mystery gift in the cart work?

Kasper Dolk's second-threshold mystery gift in the cart gave a +€30,578 revenue lift at 99% confidence over 9,868 visitors.

Is a free gift better than a discount?

It depends on the buyer. Oliver Kenyon reports tiered rewards beat discounts in one cart test (+$57k/month), while in another test removing the gift and lowering the price won +46% conversion rate.
