Are you are re-gifter?

Make gift wrap, note cards, post it on your facebook and twitter. Let people know you are ok with re-gifting.
Personally,I always try to include a gift receipt if I can. I am not offended when someone re-gifts something I gave them. I'd rather it was used, then go to waste. Not your taste/colour/size? Pass it on!
