What do you think of cubecart Billy?
I've been using it now for a few years although have neglected my site now and should tidy it up a bit. If there is anything better I would be interested although cubecart is very easy to use and maintain.

I had never come across it before but having had a quick look at both your site & the Cubecart site it looks excellent, especially for e-commerce. I don't actually do large e-commerce sites myself & would not do a site that could do as many individual products as Cubecart sites can.
I will actually look closer at Cubecart myself to see how I may be able to use it in the future, I need to look closer at the hosting requirements.
I shall download the free version over the weekend & have a play.
