This is not AIBU.
Imagine you’re disabled and can’t get to a shop and you rely on home deliveries.
you’ve just used the last of what’s left in your account to pay for that home delivery for two weeks of shopping (not the stores fault, but relevant)
you choose budget versions of items.
when you get your shopping, there are items that haven’t been substituted and are not available.
A relative goes to the same shop on the same day and more expensive versions of the items that were unavailable in your shopping are available.
isnt the store supposed to substitute? Can you get monetary compensation for this kind of scenario?
