I used to be able to use them as payment at Mobil but that stopped, and seemed like the most economical usage of them since they displaced money I would otherwise have spent from my cash balance.
I don't really need rando junk from their shop unless there's a particular deal, but the last time I looked it was just normal pricing but with a TrueRewards currency sign.
Can buy prezzy card at BP but costs 5.95 to load a card.. Then you can use it any place that accepts credit card.
