I am using a service called 1ShoppingCart for my autoresponders on my Joomla website. I'm sure you're already familiar with them, but just in case, 1ShoppingCart is like an AWeber service.

Now, I want to use them for my "shopping cart", but I'm a little unclear as to how to create the bridge between a new product page on my Joomla website and their service (where they do all of the calculations, shipping, sales tax, and credit card processing)? Do I need a plugin?

I just can't wrap my head around this and would appreciate any advice you could give.

Thanks so much . . .
