Free Guitar Hero World Tour when you buy 10 sets of exp coated acoustic strings
D'Addario EXP11 and D'Addario EXP12 acoustic guitar strings
These have gotten good reviews around the net, and I have used D'Addario strings on my bass that are great.
10 pack costs $99.99, and comes with free Guitar Hero World Tour guitar bundle according to the most recent catalog they sent me. Lists PS2, Wii, and 360.
Probably not much of a deal to most of us, but figured I'd post it anyway. If anyone is interested in a scan of the page, I can get one up, looks like an in-store deal only.
Also, you can find 10% (sometimes 15%) coupons for guitar center purchases all over the web to use with this.
