I'm in Canada, we have a rather complicated tax setup here. Basically, everyone in Canada must pay 7% GST on all purchases. People in Ontario have to pay an additional 8% PST, but just on the products, not on shipping. People in Nova Scotia, New Brunswick and Newfoundland pay 15% HST on everything.

I just used Jshop for a client's site, I love Jshop, easy to use, but their tax system isn't sophisticated at all and it looks like I'm going to have to spend a lot of programming time "fixing" the tax system to work with how we do things here.

So, can anyone recommend a PHP ecom package that's similar in features to Jshop (www.jshop.co.uk) but can handle a complicated tax setup? I particularly like the way Jshop does templates - just design the HTML and plunk in the tags where I need things to happen. It doesn't need to be a free package, I'd honestly rather pay and receive good documentation and support.
