I love the idea of a credit card number that can be used only once.
As long as the numbers don't run out (like GUIDs).
That's the best idea ever.
Too bad, the banks should know by now that if it's a dispute with a magazine subscription, to assist he bank customer, to assume they're correct.
I'm in the US, & I've never had a magazine subscription that didn't rip me off.
They even had to make laws here that prohibited companies from 'auto-renewing because the customer didn't mail a card back requesting to cancel'.
I'll go to the bookstore and send you the monthly issues if turns our that nothing works out for you, if you like.
It would help me get gifts out by getting me to the post office and help me actually go buy books I'm interested in.
If I wanted a monthly issue of any magazine, I'd do that for myself.
I'm also suspicious of them selling your name & address to junk mail companies here in the US.
As much as people hate spam, junk mail is even worse.
At least with spam, most of it gets sorted from you regular mail and I've often found my important paper mail buried inside junk mail.
But that's another issue. Anyway, you have another option.
