How to offer several free gift tiers on the tier rewards bar?

You might have noticed that when you offer two or more free gift tiers only one product is given as free while the others are charged as fully priced.

This can happen due to Shopify's limitations on how discounts are applied and combined. ( For full information, you can read Shopify's guide on discount combinations)

Our Free Gift tier relies on Shopify's Buy X Get Y discounts to give the product as free. This type of discount adds a tag to both the triggering product and the reward product:

Since Shopify does not allow multiple product discounts to be applied to the same product (line item), once the triggering product has a discount assigned (i.e., the first tier gift), it will not apply a second discount (i.e., the second tier gift). Therefore, Shopify will choose which of all the eligible discounts will apply based on the best possible discount for your customers.

There's a workaround that you can use the second or third Free Gift tier to work, but it requires some additional steps, and there are some limitations that we can not override since they follow the Shopify discount policies.

The workaround only involves some changes in the way in which the Shopify discount is created for the second and/or other tiers. The configuration on our app dashboard will be the same for all tiers and you can create them following the steps in our guide: Tiered Rewards.

The trick is to include both Free Gifts products in the Customer Gets section of the discount for the second tier. This means there should be two items reflecting here, the one from the first Free gift tier and the one from the second Free Gift Tier.

Also, make sure that the number of items on the discounts is equal to the number of gifts that you will give for both tiers. If you are only giving one free product per tier, then the quantity should be two if you have two Free Gift Tiers.

What this workaround does is that when both Free Gifts are added to the cart the discount from the second tier replaces the discount from the first tier. Since the discount from the second tier contains both products your customers can get both for free.
