Worked fine, and quick transfer.
I "reloaded" from a paypal account where I had some credit. It took a couple of tries/several attempts to figure out how to transfer the balance over (not really sure the confusion was Amazon though; it seemed like Paypal was causing the confusion). I finally got it transferred over, and everything was good. Only other issue I had was that the Amazon gift card balance was automatically "credited" or "deducted" from my next purchase. The first time I tried to purchase something, I caught this, and unchecked it, but then I forgot something so I backed out before finishing, went back and did more shopping, added something else to my cart, and then checked out. This second time checking out, I thought the gift card balance was unchecked, but I honestly didn't pay much attention since I had already gone through those steps (and all I did was add another product to my cart), so this second time I went much more quickly. Only after reviewing the order a day later (when I went to check on something), did I realize that Amazon had again automatically credited the entire gift card balance to the order. Not a huge deal, just a little annoying. Otherwise, everything went great, and I have had no other issues/complaints.
