This is nothing new to Toys R Us. In 2006 my wife and I were living in Florida when all of the Toys R Us' were closing down (as they were restructuring their franchise). Their markdown sales would start at 10% leading to an eventual 75% and then 90% and then take what can stuff in a bag and pay a $1.00 on your way out (the last day). We kept a close eye on the items we wanted so that we could possibly wait until the last moment to buy. Their sales started out almost legit on the first day. However, when they began running 25% and above off, they began raising the prices of their merchandise. This usually equalled original price or barely 10% below. By the time it had reached 75%, prices were marked up by as much as 50% in some cases. Harvest Moon (video game) began selling at 19.99, but by the 70% mark, went up to 29.99. Toys R Us hired a handful of strategists to price their going out of business sales. It looks as if they kept some of them on board... This is the same strategy played by Kohls and other "Always on sale" stores. They've already begun raising prices in anticipation of Chistmas. I believe a lot of stores will begin using the same tactics this Christmas as they realize they can't afford sales.
Should be a law against sale fraud and deceiving customers...
