I had the same issue with Starbucks cards being placed into your own account. I emailed giftme back and forth continuing to ask about that. They never would give me a reason and eventually just told me to go ahead and do it. But, at the same time, I had a horrible experience.
I purchased my first gift cards tonight from this seller. After the purchase, I contacted customer service, and had a terrible experience. There are a few things in their fine print that is strict and unusual compared to the other gift card sellers. While I received prompt email replies, the gentleman on the other end was very rude, assuming, and threatening. He even threatened filing a police report against me if I disputed the transaction with my credit card company. I do not plan to do business with them again. I highly recommend you avoid them as well.
And, they really don't need your business. I was told that they sell "thousands of gift cards every day". At just 2,000 cards per day with a minimum value of $25, he is stating that they sell at least $18,250,000 per year, probably much more. I have a very hard time believing that since I've been doing this for a long time and I've never heard of them before. Per Gift Card Granny's statistics, Giftme has $92,000 currently in their inventory. They would have to turn over their entire inventory every two days to make this happen.
