Does anybody know where I can find these CarbWise bars?

I really like the Carb Solutions/Atkins bars etc. and I'm thinking about bidding on some coupons on Ebay for Free Carbwise bars But I'm not sure if I'll be able to use them b/c I don't recall seeing them in my local grocery store....I live in East TN and I'm just wondering if anyone else out there knows if the bars are available in this area...I'm assuming that if Wal-Mart doesn't have them, I can go to GNC or Vitamin World at the mall and get them.

I know...it's a lazy post...but grocery shopping's not til next week and I don't want to make a trip before then to see if anyone has the bars!

Anybody know??
