Just saw this on Slickdeals and thought I would share. Looks like it works on jerseys, hats, etc. Lots of exclusions on the coupon, but you can always add something to your cart, enter the code and see if it applies to the item. A battle red Foster jersey is only $47 with shipping included, but add something cheap for $3 more and you'll get free shipping. They have lots of NCAA stuff too.
Code is case sensitive: MOD4TEN125

It works on this hat too!
