I'm terrible about impulse shopping, but I'm getting smarter. This year I'm waiting for the first day after Thanksgiving - Black Friday - to see what the big retailers will be up to. I'll be sure to look over the sales flyers before I spend any serious money.
And it turns out that there's a sneak preview of many big retailers' ads here. For instance, will you really be able to get an HP desktop or laptop from Walmart for $398?
