I've been using Sainsburys since last November, and my only tiny complaint so far has been ordering a single yam and getting one big enough to obliterate a small city (chain saw needed!) My problem is the minimum order thing, only partially solved by buying multiples. I'm in a leg/ankle cast at present, so can't shop. I have good friends/neighbours who happily pick up the odd thing for me, but they can't be 'on tap', and you can't do multiples of fresh fruit/vegetables etc. Multiples of booze are (too!) easy, though, and do push the bill up quickly. Not planning to open a bar just yet, though.
