D&D shop £50 off £200 spend Amex credit

[The real Swiss Tony]

Just seen the above offer on an Amex card. I couldn’t see anything to suggest that a gift voucher wouldn’t trigger the offer. Does anyone have any insight here?

Thanks

I think the whole idea is that it can be used on them. I am treating it like another dining credit…ish
