Bad experience so far. I managed to reserve and pay for bags from Morrisons and Costa over the last couple of days, but they were cancelled... What's the point of advertising for slots that aren't available? I've got 2 to pick up later from a small Morrisons and a small Co-Op, and I paid ~£3.50 each, so I will update later (if they're not cancelled too). The app needs a notification for when your selected store has magic bags available, currently you could possibly sit refreshing the app for 24h
