CardCash is for the experienced and organized on-line shopper. As with all things when you get a better deal there's always a catch. Below offers a view of what type of experience you'll get.
1) CardCash offers discounted gift cards. They get these cards from 3rd parties so around 25% of the time these cards come with zero balance so you'll have to file a claim. (CardCash has a 45 day policy and they stick to it. They do stand by their refund but it can be a pain submitting and then waiting for your check in the mail.
2) You get anywhere from 3%-40% off Gift Cards depending on the type of card you're looking for. They offer a host of Printable Cards but also many Physical Cards too.
3) If you use your gift cards within 45 days, are organized and can keep track of the claims then CardCash is one of the best ways to cut spending.
