DO NOT BUY FROM THEM!!! THEY CHANGE THEIR PRICES ON THE GO!!!

Went to the Gateway store lat night, saw a laptop that I was interested in for a good price. Had to call one of the ladies behind the counter to assist me. She then took the price tag to her colleague and came back and told me that it was the incorrect price and someone mixed up the sign, Doesn't it state in the consumer act that the price you on a item is the sale price and cannot be changed?
