Had a payment go through today for 19.99.
However i have no options at all set to 19.99.
I know what site its from even though i never received a mail.
All i can think it could be is that the user went through the payment process at an earlier date when maybe a listing price was that and left it maybe as pending.
Then the person has gone back to complete the payment after prices have changed yet its charging the old price.?.
