Thanks Drew. To be honest, having spent today working on the Paypal app I am now rethinking using it as a shop app for my client. I've got them using Perch for the rest of their site so that won't change. I might just install OpenCart for them instead. Unfortunately I can't wait for your new Shop to be released so caught between a rock and hard place.
