I know this thread is old but wanted to clarify a couple things. I work at Bloomingdales and can tell you if it rings up for 1 cent, we have to give it to you at that price. The SA's are taught only if you ask for a price check will the customer be able to see it rang up for one percent. If you bring it up to counter to ring up without price check we are told to only give you 65% off because you cant see the 1 cent price from behind counter. I am unfortunetely not eligble for this. It doesnt happen everyday but I also would not say its rare.
The Macy shoppers who posted about not getting the salesprice that merchandise rang up for should have requested a manager. If that does not work call corporate. You'll get the discount.
BTW, the SA probably kept the merchandise for themselves or a friend to buy (even though against policy). If they charged you more then what it rang up for and YOU SAW the price then they probably pocketed the money. Internal theft is a huge problem but security is very tight and has cracked down on a lot of it.
