Thanks for your reply Will.
I'm looking forward to their latest fixes from them. For me, it's the last stumbling block to having my ideal CMS system. The main issues are the complications in setting up payment providers. It would be great if the community could build in a method or area within the config settings that is more obvious to populate with the Paypal, Worldpay and other provider settings.
My main issue is I'm not a expert developer, but I'm not someone who just wants to add content, I could use Word Press for that, however, it would be nice for more obvious instructions of where the basics 'fit'.
Thanks again and I'll take your advice and put forward constructive ideas of what the previous clients expected from the ecommerce on their CMS sites.
For your info, this is a list I compiled from my client base before I was cast out from the company -

The option to use Worldpay, Paypal or Sagepay.
Support for more than one account
Product variations that can be added per product (size, qty, colour, etc)
Shipping cost and Tax than can be added per product(different none profit sectors don't pay tax on events, but do on products, so have to have this switchable)
Quantity discounting - this is a big one in that the more someone orders, each item after the first is discounted either by a set amount or by a percentage.

Hope this is useful to all. If it's useful to pass on to others, that would be great

Thanks again
Paul
