@Paul_B Unfortunately for us we just can't get on with supermarket deliveries... We have impossible substitutions, short shelf life and just poor quality fresh produce that ruined it.
I can accept substitutions in some departments - I can't think of specific accurate examples, but for instance lets say you order heinz baked beans and they were out, so you got branstons or something like that, no issue right... But we just found they always replaced stuff with utterly incompatible replacements can of kidney beans and they're out so they give you a can of custard (an exaggeration sure, but it was those levels of unhelpfulness when you've got a recipe to follow
).
Short shelf life was a nightmare, if you plan a weeks meals and order say 2-3 types of meats, and they all 'go off' the day after delivery...
Fresh veg and fruit on it's very last legs.
I'm a very efficient shopper when I go to the supermarket, I don't browse, I know what I want and why I'm there and I don't want to be in there for any longer than absolutely necessary, so my shops tend to be extremely precise to a pre-planned list..
