Any suggestions on a free shopping cart script written in PHP to use on a site selling only 10 items? Or would it be best for me to write my own?
Paypal has a half-decent shopping cart solution if you don't mind your shopping cart being off-site. For 10 items, installing a shopping cart script probably isn't worth the time unless it's absolutely necessary to streamline the shopping cart within your site.

The client I have for a website just wants a simple 3 page site, one with songs for purchase. I'll look into paypal, but they have a real hard on for having the items listed on the site so I hope paypal does that, which I don't think it does.
The items will of course be listed on the site, paypal doesn't give you a store, but rather they give you an 'add to cart' button and 'buy now' button that you can stick onto the listing on the existing website.
If you are using wordpress:

I use it on a small site and it's pretty good.
