Nestle's Honey Nut Cheerios are available in a lot of regular supermarkets and run about 2.50-3.00 euros for 375 g, so cheaper than the expat specialty stores. No plain Cheerios in the regular markets, though.

Cereals here are kind of strange. Probably a good 60-70% of them have chocolate in them in one form or another. The ones that are supposed to be healthier are expensive, and sugar-laden crap is cheap (that part is true everywhere, I think).

Americans will see a lot of familiar brand-name cereals on the shelves here, but the taste and texture are often quite different from their US counterparts.
