This post could fit in any number of categories but I though I would try the General. I am looking for a shopping cart that fits with with I need. I am not having much luck and came across Zen Cart. I can't go into as much detail as I would like due to NDA but I hope someone can answer a few questions for me.

The site I am looking for a shopping cart on is selling something that doesn't need any shipping. Nothing is downloaded either. I know sounds strange but that is all the details I can give.

Q: Can I turn off all options for shipping and have it not be part of the process?

The site will have its own registration and its own login.

Q: Can I relatively easily modify Zen Cart to take advantage of the existing registration process and login?

The site will have its own pages that show what is being sold. What I really need it to be able to drop a button on current pages that allows the visitor (who has already logged in) to just select an amount to purchase and submit. I don't want or need a formal shopping chart system so to speak. I am not sure I am explaining this good enough so let me know if you need more details and I will try to explain further.

On an existing user page I need to show a history of everything a user has ever ordered for their own viewing.

Q: Is that possible?

I am pretty confident in my PHP ability so more than willing to make an mods i need as long as everything is documented decently.

Thanks for the help.
