They had a hard drive listed on the internet for a reasonable price and when i check the availability is showed it is in stock and ready to pick up.
When i got to the store i couldn't find the item i was looking for so i asked one of the sales people where I could find it and showed the page i printed from the internet.
he said that model was discontinued and no longer available and that the new model was $15 more than the old one. I told him that was false advertising and he just looks at me like he just got caught with his pants down.
