Say you want to make a site for a business that ships things and they want a shopping cart deal, what would you use other than paypal?

nochex.com?

https://www.stormpay.com
http://www.moneybookers.com/app/
http://www.e-gold.com/

Thanks,i'll check em out.

I wouldn't use any of the linked ones given that they only handle payment - you need content management too. I suggest looking at http://freshmeat.net/search/?q=shopping+cart&section=projects&x=0&y=0 for one which would suit your needs and look after orders, stocks, etc.
