You can sign up for free at myluckyrewards dot com and get cash back at lots of sites like Best Buy, Abt, Crutchfield, thenerds dot net (I noticed someone bought a stand there), Newegg, Overstock, TigerDirect, a lot of well-known camera sites, and lots more. Lucky magazine is a women's fashion magazine that features good shopping deals.
The only thing is that you have to subscribe to the magazine, but subscriptions are so inexpensive these days that it may be worth it. They have been sending me e-mails, since I am a subscriber, and I only just looked it over. They send you a pre-paid Visa card quarterly with your cash back. There are also lots of sports sites, like NFLshop, REI, and men's clothing sites included, as well. Besides, the women in your life may appreciate it if you share the magazine with them.
Just thought you may want to check it out.
P.S. If you check out the FAQs, there are instructions for how to check out the program for 90 days without subscribing to the magazine.
