I saw an article in Times Magazine online about the savings benefits of purchasing discounted gift cards, and Cardpool.com was one of the vendors mentioned. I tried it out last night and was able to purchase an AMC and Home Depot gift card at a combined savings of 16% - not bad! The AMC gift card will be an actual gift, and the Home Depot card will be used for a tile job in a bathroom.
Update: Forget Cardpool.com. I just got an email stating that they canceled my order because they couldn't get in touch with me to verify some information. I guess they tried to call me(but no messages?) because I never got any emails until today(almost two weeks)! What a hassle. Meanwhile Plastic Jungle sent out my discounted cards immediately, and I received them within a few days - much more professional, and better communication with emails when items are shipped, etc.
I'd recommend Plastic Jungle over Cardpool.
