Quickest, dirtiest way to implement shopping cart?

[chornbeck]

So I'm doing a quick, cheap website, the guy has like 5 items he wants to sell... I'm a pretty experienced coder, just never dealt with the shopping cart thing before...

I need a VERY simple and easy (and free) shopping cart solution that can integrate with Google Checkout... I assume using the API, this could be pretty much anything, so the shopping cart is my real question...

I understand HTML & PHP very well and a bit of AJAX, but I'm really looking for something non labor-intensive as the pay for this job doesn't quite deserve a lot of hard work...

If you just have 5 items or so, why not just use G's Buy Now buttons?

I'm using CubeCart on a site with about the same requirements. It has some problems, but nothing major and it was a snap to customize. Not sure about Google Checkout, but it probably will work.

Couffin Cart is extremely small and very easy to customise. It'll also give you a great understanding of how a shopping cart works.
