Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
Why does a shop need to be certified to sell the converter.
Also set it up ahead of time, because you probably need a new aerial, or you may have a duff converter, and need to exchange it. Plus why would you not want to have digital TV if you have the converter already.
I don't think it's so much to sell the converter as it is to accept the coupons. They're cards, which means that smaller, independent stores that don't have debit/credit card scanners can't process them.
