I have the Nationwide Select card that squak references. It's a good card that gets you commission free usage abroad which is great. No avios, unfortunately, but thems the breaks.

On a slightly downward note, you only get the small cashback reward on UK purchases and not on purchases abroad, and you'll need a Nationwide Flex Plus account in order to be eligible for the Select card. I am not aware that that requirement has changed, but I have had the card for 5 years so would be unaware if it had.

I'm sure there are others out there as well.
