Thanks Bruce. That explains much.
I still can't work out why shipping is being taxed twice.
I could switch off the 'tax shipping' option and change the shipping
amount to correct for this, but that would impact other payment
methods and would be inaccurate for invoices.
I will try digging through the paypal module for an answer, and try
capturing the request that satchmo is sending to Paypal... at the
moment I'm not sure if it's Satchmo or Paypal that is adding the extra
10%.
Cheers & Thanks again
