Are you trying to broker a deal through an LHBS that everyone from your club buys from anyways? Are you planning on taking the bulk buy off their hands upon shipment?
Even if the cut for them is small I would think that any money earned with no need to hold inventory would be a no brainer for them and if that's where everyone is also buying other supplies and ingredients its a win win for everyone!
A few members in our club buy from them. The grain would be ordered, delivered, and immediately picked up. You'd think it would be a win-win no brainer for the LHBS. They broker the deal and get a cut, no inventory space to take up, not to mention the additional traffic of homebrewers coming into the shop to pick up their malt. No one would bite, even in this crappy economy.
