You probably already know how to treat your customers so they will find you & your products appealing. But let me suggest you consider this idea: Treat the suppliers of your business in the same way! Cordially invite them to become a part of your business with the title: Assistant Buyer. Explain to suppliers what it is you are doing to make your business grow & prosper. Tell them you want to share that prosperity with them. Ask them to "join your team" then work together for mutual success!
