Different shipping methods for products

Hey, we're working with the Zen Cart to setup our online store. At this point, we want to ship 95% percent of our products using USPS. The other 5% we want to ship with FedEx. My question is what would be the best approach of setting this up? We have a certain list of products that must be shipped with FedEx, but all the others must be shipped with USPS. I was thinking of adding a field to the products table that indicated which shipping type to use for each product, and then on check-out, calculate the rates based on this field. I wasn't sure if there might be an easier way of going about this, or taking a different approach. I've searched the forum but couldn't locate any threads that seem to be about this issue. Thanks

Ok, found a post that I can work with. Sorry for the post!

any chance you can share which thread you found your "solution" in?
Thanks!

Sure, the thread I looked at washttp://www.zen-cart.com/forum/showthread.php?t=90284 It doesn't give an exact answer, but gave me some advice on how to go about this.

thanks for sharing :)
