Ask your current supplier for a price savings. He will know. You want to buy good but off-brand supplies instead of name brands. He wants your business so he will tell you. If he does not, his competitor will. Toss out catalogs and create an item approved listing and do not order anything off the list without exhaustive list of approvals. Do that if you truly serious about cutting costs and saving money. Include the authorizer in your company’s bonus program tied to profitability. Once he is on board, he will be an asset.
