I have used it and I am a member on their forum - but have to say my new software of choice has to be
EROL - e-commerce shopping cart software e-commerce solution provider Shopping Cart Software from Erol all your e-Commerce Shopping Cart Software solutions
They are offering 50% of at the moment and have a 30 free day trial option, the reason it suits me is that it is html based so suits my skill set.
Nice people there also.
