However if you're a store that breaks some secret agreed max discount threshold, then a manufacturer may choose to stop supplying you with said product. Sometimes this only applies to the 'advertised' price on something. This is why you'll see paper ads that say "price too low to print, come on down to the store" or online places like Amazon where it says "see price in shopping cart" and won't tell you the price until you're at least pretending to head to checkout.
This is called MAP, or Minimum Advertised Price. In most cases, MAP is an agreement between supplier and retailer that states a store cannot advertise in any way, shape or form below the set MAP laid out by the supplier. It's a rule set in place to avoid driving down the value of high profile items in the marketplace. Basically, it protects the supplier by maintaining a polished market presence, and the retailer, by maintaining a set margin of profit on said items.
Like Hobie said, once the customer is physically in the store, or in the online checkout area, anything is game as it is assumed that the customer has already made the decision to buy at said store. This is how retailers get around the MAP agreement.
