I need a customer friendly shopping cart made for my website. It must be compatible with PayPal and Worldpay, and I would like it to be able to be updated later by myself when I add new products etc. It needs to have at least two currencies ($US and $Canadian). It must hold about 200-300 products. It needs to add tax. I would like all my products added, with pictures for each product added also in a nice professional way. I want a nice, professional shopping cart which will be very easy for the customer and myself to use, and fully able to have all the features that my business needs to it to have. (printing packing slips, keeping track of all the orders, etc.) I am on a mac computer, so it needs to compatible with it also I guess.
