Hypothetical; your coupons are those shown in your own account.
Alex signs up
Alex follows the link on our coupon page. The referral link carries the offer, so Alex types no code, then verifies the email address when GTBuy asks.
Alex reads the coupons
In the account, Alex notes for each coupon whether it is for items or shipping, its minimum spend and its expiry.
Alex uses one
When paying for the hoodie, Alex checks whether the order meets an item coupon's minimum. It does not, and Alex decides not to buy extras just to qualify. Later, paying for the combined parcel, Alex selects a shipping coupon whose conditions fit, and sees the total fall.
If Alex had seen no coupons
Alex would confirm using our link, check email verification, wait and refresh, then contact GTBuy support. We cannot look into accounts.
