If I have visited a website, and moused around looking at stuff I can buy, I don't mind the targeted ads showing up elsewhere. I suppose the intention is to remind people that they looked up something and that it's still available. I don't mind that.

But as jford indicated, if I've already bought that "something", it would be helpful if the targeted ad showed me something different, maybe related, instead of what I already bought.

If there was a way for the PGMusic add to figure out (say), "this guy bought our recent basic upgrade, I would like to show him that there are Xtra Paks available". That wouldn't be intrusive or "pushy" to me, only useful information.

In any case, I've never found any of the targeted ads to be offensive.
