Click on eastbay and either sign in or sign up for an account (free). After you have all of this done you will receive 50% cashback on everything you buy at eastbay (for today). I just dropped about $400 but will get half of it back. You do have to wait 60 days but you will get it back. I have done this numerous times before, but not for this much cashback.
The custom made jersey is usually 75, but would be 37.50 after the cashback. Honestly they don't check the names. I have a Warren and McGuffie (yeah that sucks) jersey that I have bought from Eastbay in the past. Not too bad of a deal.
