Great to hear Flip. The burden of proof is on the merchant, and obviously they could not produce a picture of a ginger making the purchase or a signed slip to validate that it was you.
And for those who might be curious with what card to go with, American Express is by far the best card to have as a customer when dealing with bogus charges. When I see an American Express chargeback I kiss that money goodbye. Sadly, American Express is not well received in a lot of locales.
