Huge fan of this app - friend told me about it over lockdown and after I'd had my first "magic bag" I was hooked! The basic idea is that you pay for a lucky bag of food from a local retailer which would otherwise have gone in the bin. Picked up a bag from a M&S petrol station shop last night, cost me £4, got two large packs of salmon, two panini wraps, two packs of sandwiches, a side salad, a bag of mixed veg, and a pack of melon. Greggs also do bags which the kids enjoy - most of the bags we've had from there have a couple of the bakes, sausage rolls, cakes, pastries.
Yes it's all short-dated, yellow sticker stuff but lots can be frozen. Or eaten the next day. Definitely worth looking at if you're flexible about what you eat. Lots of restaurants do it too, although pick up times can be much later in the evening.
Any other fans???
