It happens all the time. Practically every week you will see adds in the newspapers, stores having sales. Electronics shops, selling large screen television sets will advertise very low prices. When you get to the shop, no bargains to be found. The television sets are gone. One wonders if their were any television sets available at the low prices. Some shops will advertise low prices, have one or two sets available, and no more. Their salesmen will try to sell the more expensive sets. Just a ploy to get you into the store. Happens all the time here, no doubt it happens in Europe.
