Sure they could. But if you're buying a sufficient volume to make it worth their while, they'll likely be willing to sweeten the deal...or at least talk about it. That's haggling.norcaldiver wrote...
But that does go both ways tho. So to take the other side of that coin for fun.....If a shop sells 100 BCs a day and you come in and ask for a price, couldn't the guys say "ya know take it or leave it, I sell these all day, if you don't get it someone else will" Sufficient volume = he desn't have to give you a break if he doesn't want to.
All bets are off if we're talking about a monopoly or a cartel, though.
