Firstly your post doesnt say what Card it is, £10, £20, £50 whatever.
Secondly if it's £20, judging by the posts, you'd accept £14 or $18?
Why are we paying more if paying in Pounds? Considering conversion is £0.6 - $1
So we can either pay £14, or if paying in Dollars, pay less than £12? I dont get it. :s
