Looking for a shopping cart plugin (with dropdown, shipping features)

Hey WP,

I’m looking for a plugin that will allow me to sell my (my clients’) product by the pound (lbs) and shipt out to customers. My client is a farm that sells meat. It would be great to have a feature that would allow the end user to have a dropdown and choose a quantity.

I could code this up myself but I’d rather just use something that been proven since I don’t have much time for development, debug, test,debug,test.

I was looking at wp-ecommerce but didn’t see anything that jumped out at me.

thanks
