Google only gives me ads for products I've already bought. I'm not sure which genius thought that kind of targeted advertising was a good idea.

Perhaps if I used gmail, so they could read my emails and see what I've bought already, I wouldn't have this problem. I'll pass on that idea though.

Using gmail only makes it worse, as far as I can tell. I don't get the impression they pick your emails apart enough to distinguish between "bought this" and just "looking at this". I guess there's also the chance that, say, after buying a Frobnitz, you'll want to visit a Frobnitz-seller's website to buy accessories.
