Create New Product form improvements

There is some information that we should be able to enter into the new product form that
would greatly improvement our management of the unique items we sell.

Please include on the input form a section for store-only details about the product. The
information in this area would not appear to the public. It should include fields to enter the
dealer cost of the item; name, address, phone, and other contact info of the source for the
product; and a comment area to add any other pertinent info for when we go to resupply. It
would be helpful to have this info in the store control center right alongside the product.

I'm sure that's just a start. What other useful information would other users like to see in the
"Create New Product" form?
