Particle, Ok I have a question - Assume you have a product such as a t-shirt that requires options (size, color, etc) to be set before adding to your cart, how can you just click add to cart and have it added to your cart if you don't first go to a products detail page first where these options can be selcted? The ideal situation is to check if the product has attributes (options) to be set and if so go to the details page otherwise go straight into the cart. I don't know why or how you caused an error on the shipping page or what you were using when you did - the online demo, the download demo? I'm not the author of that cart so who knows. Give me a link to a cart you have designed and I will get an error to generate in a few minutes. Not sure why you turned this into a bash session instead of trying to help someone on their quest to create an e-commerce site for their client. Anyway, if you have the time and budget to write your own e-commerce site than by all means do it, but I suggest you use one of these off the shelf carts that you can extend and customize. And if the IBuySpy cart is a piece o' ... then why on earth would anyone suggest it as a reference for building one.
