At the checkout of your retailer's website , there is a small box requesting you to enter code. Almost all retailers will display the amended basket total prior to taking payment.
But if you still can't find any place to enter the code , don't worry. Every site has a different lay out. Sometimes you might have to click on something to reveal the box.
Codes may be referred as :
- Promotional code
- Coupon code
- Discount code
- E-Voucher code
- Promotional Shopping Code etc
Look for similar codes or phrases which can take you tot he right place.
