Beat clutter and save money by swapping goods. Stuck with a gift card you don’t want? Sell it to Gift Card Rescue and then buy a gift card you actually want for cheaper than its monetary value. For an online-shopping experience, try Dig ‘n’ Swap, where you post pictures of things you’d like to get rid of, then dig for the stuff you want, then make a swap. Want a local experience? Try FreeCycle, which has online branches across the country.
