It sounds like lots of stores in the US are having special sale events starting as early as tonight. Take a look at your store's Facebook page, check your emails, or ask when you are in the store to see if they might be having one.
A reader writes that her store is having an event tomorrow:
I don't know if this is happening everywhere, but I just got confirmation that my store is putting about half of their current inventory on MD tomorrow to make room for all the stuff coming in after the LA port issues were cleared up. I'm guessing this relates to the giant WMTM this morning, so maybe lots of stores will have big MD selections tomorrow!
