If you're wondering if it's worth being on a store's mailing list, it is. Seriously. Yeah, you're going to get more spam than store credit, but it really only takes me a few minutes to delete the spam. But sometimes the spam is awesome, and that makes it worth it (in my opinion). Also, if like me, you primarily shop online, Ebates is my new favorite thing. Yes, they track your shopping and browsing history, but so does Chrome and all of the internet in general unless you're using Tor, so at least with Ebates, you're getting some reimbursement for it.
I hope you scored some awesome finds this week!
