I was so thankful that I could get this gift card on the Amazon website because I just had back surgery and I couldn't get out to the store to get my daughter something for helping me for a week. I just really wanted to show her my appreciation for everything she had done. I didn't know that you could do this and then I Googled it and it said I could. It was so effortlessly and so easy to do. I definitely will be doing this in the future now that I know how well it went.
