not sure about america but in the uk and europe that sort of practice is illegal and contravenes competition law. could even result in a prison sentence for those found gulity same as price fixing
Since when!
You can't force anyone to stock the product you make.
Say you produce an item, and start selling to a national supermarket. Over a few years the product sells well, and the supermarket ramps up the orders.
On the back of this business, you expand your factory and take on more staff, so from the early days of just you and your wife making the product in your kitchen and selling 50 items a week to one trial supermarket store, you now employ 50 people in a retail unit, with machinery you have taken out loans for to buy to meet your current production targets of 50,000 units a week to the supermarket to stock nationwide.
Who has the power to dictate in this arrangement?
You, or the supermarket?
To you, the supermarket is you life, if they cancel the order, you are bankrupt.
If they lose your item, well, no big deal then still have 20,000 other items in there store they sell each week.
If they say they need you to cut prices what do you do?
If they want money from you to stock their products, what do you do?
Amazing as it seems this is exactly what was on UK TV a few years ago, an Apple farmer saying a supermarket was demanding more money this year (I think it was £30,000) for them to stock his Apples, if he did not pay them, they would not stock his apples, and they would go rotten and lose his business.
Amazingly it was legal, I'd call it blackmail, but there was another legal term given to this kind of arrangement, Basically they want the supplier to pay them to stock the suppliers product.
