This is incredibly helpful, thank you all so much. I will give it a go via Tesco at the weekend, and if they let me down, I will go for Ocado. (The black pudding substitution finished off any interest in Sainsburys.) Probably this is a silly question but....do you tip the delivery guy? My husband always tips eg pizza guys a few pounds which I find different somehow from the Tesco chap, but maybe the guy would expect it?
