My sister gave me a $25 BestBuy gift card last Christmas. I went to BestBuy, and found that for each of the 3 different things that I needed, I would spend less by buying it on Amazon, even with the gift card. Tax software, for instance, was $49.99 at BestBuy, $16.99 on Amazon.
I'll have to look for that. My in-laws give me a Best Buy card every year for Christmas and half the time I use it to buy their Christmas gift the next year. Amazon gift cards get spent right away.
Also if you ever get a prepaid credit card as a gift you should just spend it on an Amazon gift card. That way you don't need to worry about expiry or going over the credit card's "limit"
