Try and buy an advertised item at HiFi Corp - 25% chance of succeeding!

I decide to get a new 4k Smart TV 50 or 55 inches. Go online and all of these HiFi Corp popups appear. I select 4 options and phone my closest branch. Only 1 of the 4 in stock! But they did try to sell me an "upgraded" version of one of the "out-of-stock" ones. I'm sick and tired of these "specials" that they use to get your feet in the door and then attempt to get you to buy a more expensive model. Surely this must be ******* and **********? Enough is enough!
