[I know 'cuz I was thrown out of the Nashua NH store for doing exactly that. I tried to buy 7 items (3 CD's and 4 DVD's) at Target and asked for a gift receipt for each one so that my nieces and nephews could exchange them for others if they already had those titles (who the bleep knows what CD's and DVD's teenagers have/like???)

I would have been FURIOUS!
I can't believe they did that! I tell you what, I think I would go to Target corporation on this one. I would demand an apology and some GC would be nice too, even if you never want to step foot in their store! Good luck.
