I actually do sometimes - on those text-only Google ad results (the only kind of ads I ever see), whenever I happen to be actually looking for something explicitly and they seem to be offering it. I don't see anything wrong with that, those ads do meet my "non-intrusiveness" criteria and I don't see why I would purposefully avoid them if they're actually advertising exactly what I'm looking for - if I didn't go to a specific retailer's site directly it means I'm open to reasonable suggestions...
