BigBoxFree gift with purchase, wired into your bundle
Gift-with-purchase is one of the oldest offers in retail because it works. BigBox makes it a reward tier: when the box reaches the threshold you set, the gift drops into the cart automatically and is discounted to free at checkout. No codes, no scripts, no theme edits.

Set up a gift tier in minutes.
Choose the gift
Pick any product from your catalog as the tier reward. If it has variants, shoppers choose the one they want before adding the box.
Set the threshold
Decide how many items unlock the gift. Gifts can sit alongside discount and free-shipping tiers in the same bundle, up to five tiers total.
Let checkout do the work
When the cart qualifies, the gift is added automatically and discounted to free at checkout through a Shopify automatic app discount. Gift items never count toward tier progress.
A gift offer that behaves in production.
The details that usually break gift-with-purchase setups, handled.
No code to type
The discount applies automatically at checkout when the cart qualifies. Shoppers see the gift, not a coupon field.
Real order lines
The gift is a genuine cart line discounted to free, so fulfillment, inventory, and reporting handle it like any other item.
Variant choice
A gift with sizes or colors is fine: the shopper picks the variant before the box goes in the cart.
No progress gaming
Gift items never count toward tier progress, so a free gift cannot unlock the next tier by itself.
Discount guardrails
BigBox checks that the connected Shopify discount exists and is active, offers one-click repair, and recovers automatically via discount webhooks.
Measured like everything else
Gift tiers show up in the same funnel and paid-order analytics as every other bundle, so you can see whether the gift pulls bigger boxes.
Free gift questions, answered.
How do free gift tiers work in BigBox?
A tier's reward can be a free gift: one product you pick. When a shopper reaches the tier, the gift is added to their cart automatically and discounted to free at checkout through Shopify Functions. If the gift has several variants, the shopper chooses one before adding the box, and gift items never count toward tier progress.
Does the gift show up as a real order line?
Yes. The gift is a real Shopify cart line, discounted to free at checkout. It appears on the order like any other line, so fulfillment and inventory treat it normally.
Can shoppers pick the gift variant?
If the gift product has several variants, the shopper chooses which one they want before adding the box to the cart.
Can I combine a free gift with other rewards?
Yes. A bundle can have up to five quantity tiers, and each tier has its own reward: a percentage or fixed discount, a free gift, or free shipping. For example: buy 3 for 10% off, buy 4 and get a free gift, buy 5 for free shipping.
Do I need a discount code for the gift?
No. The discount is a Shopify automatic app discount applied through Shopify Functions when the cart qualifies. Shoppers never type a code.
