The code works site wide, but I'm not sure for how long. Just this w/e I said I needed to start looking for a sale on memory foam mattress toppers, as mine's getting ragged. (They last 3-4 years usually.) Today, I saw Kohls has them on sale. Using the codes, any size is ~$25 shipped. They're usually at least $50 on sale. (Search for Five Zone Memory Foam Mattress Topper)
Chris, Thanks for letting us know of this offer and my comments below are about Kohls, not your kindness and helpfulness.
I have to say that Kohls' online purchase system is PATHETIC, because several times now, after I have put in my credit card info and everything, it tells me that the items in my bag are NOT available. I've even gone back again to see if I may have mistakenly 'missed' the note that the item is NOT available, but everytime, their system will allow me to put the same item in my 'bag', but after I enter all of my personal info, and hit the FINAL button is when it'll again say the item is not avail.
