I'm a huge fan of Groupon and all the daily deal websites. You can get some really amazing buys but you can also feel silly when you realize you'll not be able to use them. I will admit I have purchased a few vouchers, printed them then realized I won't be able to use them in time. Rather than throwing my money away I resell them! Luckily, I've only done this a handful of times. Here are a few of my favorite sites to resell those vouchers.
