Have you ever checked our Raise.com? I haven’t written about them in about a year, but they are a great site for buying already discounted gift cards. Even better, when you go through my link and sign up you should get a code that entitles you to a $5 discount off your first order. You only need to spend $1 out of pocket to use the code, so you may be able to find a partially used gift card with a remaining balance of $6-$7 and pay $1-$2 for it 😉
You also have the option to buy full price gift cards (which are better for gifting) and you get back a percentage in “Raise Cash” that you can use on future purchases as if it were real money.
I expect this code to come to your email, but they have changed this whole referral thing since the last time I wrote about Raise. If you go through the process, please comment and let us know what steps you took to claim the $5 freebie.
