Within member.pcbway.com/Member/balance it states [To make it easy to buy PCB or PCBA as you go along, you can deposit an amount of cash in US dollars to your account. You can deposit cash using VISA, MasterCard ,Western Union,Bank Transfer,WebMoney,Credit Card, or use PayPal. If you are using a credit card other than the ones we accept directly, you can only deposit through PayPal. Once deposited, buying an PCB or PCBA is a one-click action. You can find receipts in your transaction history. ] But upon entering the amount in USD i.e: 125 or 200 and clicking "Apply to your balance" it returns "Invalid coupon code". -Am I doing something wrong here, I assume the "check" button is to check if a transfer has been completed, much akin to refreshing the page. I would just like to be able to credit my account, as I'm a lone developer on a lower income. Thanks :D

Are you saved my credit card data?
