Advice Please - Shipping

Hi,

I have a local test site here and have configured Zen cart. At this point I am ready to go live but require some advice.

How do you handle drop shippers?. What is the best way using Zen Cart?.

I have searched for a solution in these forums but did not find any.

Is there a way to specify shipping per product or some process workaround I can use?. I already installed and looked at osCommerce on a secondary test site, but it was not my cup of tea.

I just need some pointers on how to process orders for drop shippers using Zen Carts built in functionality. What if a customer picks products from different drop shippers?. I tried a flat rate but that does not cover the logistics of being charged several shipping rates.

Thanking you in advance,
