IKEA is having a midnight madness sale on Friday, June 18th (Canadian locations only, excluding Quebec) from 8pm-12am. I've attended a midnight madness sale before and they usually have a group of items reduced in price and then every hour they offer 50% off one selected item. Even if the "special sale" item is of no interest to you, watching the frenzy of people converge on the sale bin is definately interesting to watch. It doesn't hurt to be eating a warm cinnamon bun while doing so either.
