This is a great thread. ???
I’ve never ordered groceries on line, but now I’ve been warned!
No, no.
It is just the hilarious ones that are listed here.
Tesco are usually very good with substitutes if one opts for them, and one can use the up to 55 letters and spaces to be more specific about substitutions.
One can allow substitutions for some things but not for others if one so chooses.
For example, I order one type of cat food, but I flag that substitutions are allowed for that product and add the picker note
prefer senior prefer gravy but please send something
Though they do have an override policy for some things, and substitute even if not flagged, such as milk, non-dairy milk alternatives (eg soya drink), and toilet rolls.
I have never had a bizarre substitution from Tesco, though I have declined some at delivery time, such as when someone, doubtless well-meaning, sent lactose depleted cow milk when Alpro unsweetened soya drink was not available. But I am vegan.
