Interesting. After a while of not doing much on GB, I listed a few guns and sold them. Got the bill notice and went on line to pay them and they said my credit card wasn't valid. I looked and it expired this month, so I went ahead and tried to use the same credit card number. It came back as not allowable. You can't use a credit card on file that expires the same month as the bill hits. I went ahead and gave them a different credit card and I didn't receive the $2.00 fee the folks are referring to. I'm guessing the reason is because the card itself wasn't expired, it just wasn't valid to pay the current bill. Tell me if that make any sense to anyone.
