Draclvr,
It's already done and I really enjoyed solving it but sadly it's No 304 so you'll have a little time to wait
Clare,
All I can tell you is that I have been using PayPal for years both buying and selling. In all of the hundreds of transactions I've never had a single problem or a single complaint from my Credit Card Company.
I think Albert's comment may arise from the time when PayPal used to make a little posting (1 cent from memory) to your account to check the validity of your info when you joined - some credit card companies didn't like that but I don't think PayPal do that anymore.
Anyway ... I repeat ... I have alternative arrangements for anyone who doesn't want to use PayPal - just e-mail me.
Peter
