Makes me wonder what best buy plans to do with the gift card once they own it? Will they go buy stuff at retail from these retailers? I get the idea of the program, but not sure it will actually work out in execution.
Best Buy doesn't do anything with the gift cards, Plastic Jungle does. Plastic Jungle takes the gift cards you sell to them (e.g. for $0.80 on the dollar) and resells them to other people (e.g. for $0.90 on the dollar).
Getting RZ points back from this method is similar to you buying Best Buy gift cards at $1:$1 directly from Plastic Jungle with the money you got from selling your original gift cards. Plastic Jungle probably gets a discount rate on the Best Buy credit from the partnership, and obviously Best Buy likes selling more credit to their store. And if you feel like it, you can take a small hit to liquidate unwanted gift cards you would never spend anyway. Everybody wins.
