I just went and picked up my Digital Converter Boxes at WalMart.
After the coupons these were only $10 per box. Everyone says that even if you don’t need them they do improve reception (I plan on testing this later today). Also someone you know might need them & might not be as diligent about getting the coupons as you & they might run out? Also Dad & I believe that there will be enough ppl who are stupid & have no idea what is going on so when this goes down on Feb 1st they will be in demand (read eBay).
