I manually enter credit card payments through a different provider. I do NOT want to use Intuit's payment system. However, even though I've turned off the accept credit card option in my account settings, the Receive Payments page automatically checks the credit card payment box. This has resulted in major hassles when a customer is inadvertently charged twice.

There is no reason why that box should be checked by default, except that it drives financial traffic to Intuit. Intuit is profiting off their customer's inconvenience. In my opinion that is unethical.
