Replacement card...£10 for postage alone???

My card is damaged apparently, so your help centre says. But a new one is £5. OK fair enough. but postage is £10? That’s a pee take if ever there was one. You’re making a significant profit on postage.
I’m sticking with my damaged card and you have gone right down in my estimation. I guess profiteering will lead you on the path to become juts like all the other banks.

Isn’t it 10 for issuance + shipping altogether?
