I do suppose I appeared a little hopeless in my last post - Also, Money Man, I 'm sure you're not alone in having Visa cards spread across several accounts, successfully...
The problem is that if one of your accounts is shut down, for any reason, that Visa becomes flagged. When you reenter that card info into your new advertiser account, it will be rejected. However, you can write FB and have them lift this 'ban' on your Visa...Typically, these accounts will end up getting 'axed' in the long run. Switching to Paypal seems to 'take the heat off' though...
Also, Money Man brought up another great point - gift Visas are your friend
