It honestly depends on the ads, but the one I definately avoid is Walmart. Those people are out for blood! Two years ago, a friend of mine was actually thrown into a cart by people trying to get the GBAs. Not pretty!
Last year I made arrangements with another BF mom and she went to Wal-mart while I went to Circuit City. Worked out well for both of us. Hoping to do that again this year.
Thanks to this site, so far I know I want to go to Sears and Radio Shack (same mall) but prefer to mall shop AFTER hitting everywhere else. Will wait to see what TRU, Kmart, Target, Circuit City and Value City to determine my final game plan.
Keep up the good work guys!
