This is how you use a coupon code:
A discount code at Spreadshirt is available on the page Spreadshirt Coupons & Discounts, for example in the course of discount campaigns. You can use one discount code per order under the conditions stated.
Coupons holding credit can be gift certificates or coupon codes you may have recieved from our customer service. You can use it in addition to a discount code. Use it as often as you like until it’s used up.
