What do you have you want to get rid of?
I used to buy home depot gift cards from somebody >$1000 at a time for 0.7x face value (work gave them to him instead of a cash bonus), but competition increased and he started getting 0.85x or more. It's not worth my time for a 10% savings (driving to meet up, check the cards are valid and he hasn't scratched pins, drive home).
