When you say they don't support Apple Pay do you mean (subject to available funds/limit) or capped at £30?
Because (by rights) anywhere that's contactless should be aOK with Apple Pay.
'But as we all know Apple Pay still functions up to the value of £30.'
Yes the contactless allows for normal Apple Pay payments just like anywhere else in the UK that takes contactless but you won't see the Apple Pay stickers on any Tesco windows.
