I saw the below in a post from December (of course, saw this after I renewed)...not sure if still valid:
I just renewed my membership for 1 year with an offer that got me a 2013 US Open hat and an undated US Open Cinch Bag. 2 items! It was source code 818. I thought it was a great deal. It's good until the end of the year. I wasn't due to renew until February but I decided to go ahead and do it now. It added onto my membership.
Discounted Prince rackets, cheapest string I can get, strung at 60+ pounds, clothed in any name brand under $10.00 mixed with Target.
