According to a deal website, thesportsauthority.com is advertising the Karma for $329.99, then code TSA_25FF01 is a coupon for another 25% off, taking the price to $247.50, then the usual $20 rebate is also available.

I personally don't need a Karma, so I didn't take all the steps necessary to confirm this. I never found a spot to insert the coupon code, maybe it is after you enter all of your shipping/billing information at checkout.

Anyway, hope it works for the Karma-less out there.
