Due to changes with how Amex purchases work when completed on SignsSeen, we have stopped accepting American Express as payment on our website. This was discovered when we refunded a recent AMEX purchase. PayPal kept ALL of their fees....usually they add the fees for the transaction back in when the refund takes place.
I would much rather provide a refund then ship a product the customer will not be happy with. But, as in this case, if a refund causes me to lose an additional 3%, then it is a form of payment I will no longer accept on the websites.
Should you need to pay with American Express, we can accept payment over the phone.
Thanks for the understanding.
