Coupon InfoThere are generally two types of coupons that you will come across. The best kind are the ones where all you do is click on a coupon link on the web or in your e-mail, and the site you visit takes care of your discount automatically, often putting it directly into your shopping cart. If you don't see the discount before finalizing your order, something has gone wrong. If you try the coupon link again and it still doesn't work, the coupon may no longer be valid.

Slightly less convenient are the coupons where you have to enter a coupon code at some point - usually during checkout. The problem with coupon codes is that you often can't be sure if the coupon worked until you're in the middle of checking out and you've already entered all your information. In some cases, it's hard to determine if your coupon worked even after you've checked out. So when you get your final invoice, make sure the discount was applied! Some sites, thankfully, let you enter your coupon code before you checkout, so you can see the discount in your shopping cart.

Many online stores also offer discounts where you don't even need a coupon. Just make the minimum purchase, follow any rules, and the site will automatically give you the discount!
