As luck would have it I've recently finished a shopping cart that uses PHP and MySQL. 🙂
It is fast, secure, reliable, easy to update and can be managed from any computer with an internet connection. I'm also confident that it could easily handle several thousand items.
But rather than me telling you how easy it is to use, why not try is out for yourself? It's at www.parkerandhobbes.co.uk
