I'm going to try this idea again as it is important to my business and I think it would be important to all who integrate with POD suppliers. We need a method to be able to assign existing products to different suppliers if we need to. The idea of connecting hundreds of products to one supplier, then something happens where you can not to do not want to deal that supplier and need to switch scares the heck out of me.
If this happens you would have to basically start from scratch which does not seem like a good idea to me.
