IF it were price competitive, quite possibly. But you run into hazmat shipment problems, at the very least. Big dealers already deal with that.
You really think a company like Kodak or Fuji pays Hazmat fees, the larger the shipper the higher the discount, because the carriers want the business, and big companies that ship chemicals that might be considered hazardous simply work that into the discounted rate. Say a shipment costs Joe's photo store $25 and $40 in Hazmat fees, the same shipment might cost Kodak or Fuji $2.50 and $1 Hazmat fee. Smart dealers order the stuff drop shipped to the customers address, so that they get the cheaper shipping.
