So you want to buy wholesale...
The only way to buy wholesale is to buy from the mills. You can negotiate trade pricing with a lot of places, or you can order from a broker, but this is not "wholesale." The question is if you qualify for an account direct with the mills. And they are the only ones who can answer that, so you will have to contact them directly.
My guess is you would probably not qualify to have an account direct with the mills, but what do I know? Try them and see, or go the broker route, or expect trade pricing with your retailer.
PS If you have an account they will arrange shipping, which will be a minimum or $.XX per SY. People who drive to Georgia to get a few rolls are stupid, it costs more than having it shipped when you count everything.. Don't think you are finding some magic way that no one else has never discovered. Ditto if you use a broker. But the stores "open to the public" or "mill outlets" or "direct from Dalton" aren't wholesale - they are just stores that may try to move some volume with somewhat lower margins because they a) aren't paying any freight since they are literally next door to the mills, but you will be charged freight if they ship it to you, and b) they aren't providing any services like installation, since most clients are phone calls or from a few hundred miles away who think they are "getting over." They count on moving some volume because of the general public coming to Dalton to shop. Actuality is you can get essentially the same price and probably better service at a good store where you are.
