I used to buy ThemeForest products and recently signed up for Amazon S3 but for the free account. When I was on the 'Pay now' page in PayPal for ThemeForest product, I decided to go back select another theme, but it automatically deducted $1 from the bank account without any reason. Similarly, when the Amazon S3 account is free, don't know why $1 transaction was processed. Looks like I have to stop this before getting further unwanted transaction. Any workaround for this?
if you are using it first time on that site and your payment is thru paypal then they use this for card verification.
