TooGoodToGo, anyone done it?

ironcheftoni thought this was worth mentioning said

at a group dinner last weekend, a friend mentioned an app called Too Good To Go. An app where you can sign up to purchase the leftovers from restaurants and bakeries at rock bottom prices. I guess sort of the IRK of fresh food so to speak. I signed up but have not purchased anything yet. In my area, there is Tiff’s Treats, Whole Foods (bakery and prepared foods), a boba tea shop (they sell drinks that were not made to customer specifications by mistake instead of throwing them away), donut shops (Shipley and Krispy Kreme), a macaron bakery and a local Chinese restaurant. Have you done it? Would you do it?
