Chuffed to be approved for this to add to my arsenal of overseas cards. No panic now to pay off cash advances ASAP. Will let the DD do it.
Going to answer my own query here. I asked them directly & this is the answer I received.... "You won't be charged any fees on any non sterling transactions done online or otherwise until 31-08-2023 if you are approved of this card." Unfortunately, I'm not approved for the card & I can't swap my present Barclaycard Platinum card for this either. Oh well, life goes on....
I looked at the wrong tandem card, they do a credit builder one with only low limit. I think the max limit on their other cards is £12k.
Tandem gave me 6k credit limit off the bat.
I don't know but will try and find out. I know someone on here applied for version 1 of the travel card (this is at least the 3rd version) and when version 2 came out with a longer offer period, they extended the date for them.
