Your plugin is beautiful and I am looking forward to getting my shop open. I have encountered a problem, however, because I want to sell both digital and physical products.
I decided to turn off the Paypal Profile Shipping Settings because I didn’t know how to configure my current Paypal service (basic web payment) for both the digital and physical products. But guess what? After I get over to the Paypal login window, when I click on calculate tax, it STILL adds in the shipping and tax I have configured in Paypal. So apparently it would charge customers extra shipping for downloads as well as tax, when tax is not levied on digital downloads. Wondering why the Paypal Profile is not OFF? I have unclicked it in “Use Paypal Profile Based Shipping.” I have PHP 4. Do I need another workaround?
