Yeah yeah I know how selling and growing usually works. The grower sells to the dealer, who inflates the price and, well, deals it. But say that it isn't being run the way it usually is. Say it's being run like a bank (kinda.) the grower fronts an ounce or two to 3 or 4 friends who happen to know how to sell. Assume the friendealers don't try to rip the grower off. (this method is a really common thing around here) Say each dealer gets $100 for that ounce (not a realistic price I know.) this 100 is then split between the dealer who sold it, and the grower. How, in your opinion, should it be split up? I know people who go 50/50, 60/40, 40/60, hell all the way to 85/15. But what do you think the ratio should be? And in who's favour?
Let's simplify this. The grower is a wholesaler, the dealers are retailers. Like any business transaction, its up to each party involved to decide what they need to make them happy, negotiate for it, and get it.
That would be true of a traditional distribution model, where the dealers effectively pay wholesale prices for the product (determined by the wholesaler), and can charge whatever they like for it in retail sale (to the point that the market can bear). Or it could be a "credit" model, where the wholesaler expects to get back a portion of the retail.
The wholesale/retail ratio "should" be whatever makes the respective parties happy, period. If the retailer is buying larger quantities, he should expect a slightly better per/quantity price for economy of scale.
As a place to start the discussion, 50% markup isn't an uncommon ratio between wholesale and retail, but that depends on all kinds of market related factors. If the dealers are taking on more risk, they can reasonably expect to get paid more to cover that risk.
Now, as to the business model, "credit" type business models only work under certain circumstances. In the illegal drug trade, since credit disputes can't be taken to court, they usually only work when the one extending the credit also has the "muscle" to enforce collection. Needless to say, since most growers aren't budding (get it? ha!) mafiosos, as far as I know, things are generally not done this way. If I were a commercial grower (and to be clear, I'm not, never have been, and never will be) I'd insist on getting paid up front for whatever I grew. If the retailers know how to inflate the prices to get more for the product, good for them. Likewise, if they lose/smoke/or can't sell the product. . .again, their problem, not mine.
