why do some manufacturers insist on vendors charging what they decide is the proper price for an item? once a vendor pays whatever price they agree on to buy the item why or how can a manufacturer dictate the next sale? if a vendor wants to work on a smaller margin than another why is it legal to stop that? yes, I get a cheaper price from one vendor will undercut sales from another but won't the cheaper vendor order more to keep up with demand? the manufacturer will still make the same amount of money if vendor A buys 10,000 items or they sell 1,000 items to 10 vendors. price fixing should be illegal and I don't understand why vendors (or the law) allows it to happen.
