I've dealt with numerous purchases from PlasticJungle and GiftCards.com

I prefer dealing with GiftCards.com---

In the past 3 years, I've probably purchased 40-50 gift cards through GiftCards.com, and of these purchases, I received 2 GiftCards that had issues from GiftCards.com and both times, a prompt refund was returned to my credit card. I've only made about 6 purchases from Plastic Jungle, but haven't had issue with their gift cards.

If you do ever purchase a giftcard second hand, be sure to check the balance immediately after purchase, and then check it once again before you plan to use your gift card.

One of two problem gift cards purchased from GiftCards.com showed a $50 balance after receiving it, and then checking the balance prior to using the card a week later showed a 0 balance. Apparently the card was completely drained depsite me keeping it in a secure location since checking the balance. GiftCards.com determined that the person that sold the card to GiftCards.com copied the gift card account number, got paid, by GiftCards.com, then drained the giftcard after I had received it. Nevertheless, GiftCards.com did a full refund on the drained gift card.

Unlike Plastic Jungle, GiftCards.com uses their own employees for their customer service center, and their customer service center is staffed 24/7. Also GiftCards.com seems to ship plastic gift cards much faster than Plastic Jungle.
