Not a bad deal. I got this last time it was on sale. I also have a blanket made of similar material it's just thick enough for people that live in places that don't get insanely cold. It's also 300 TC, so not as bad as the flannel sheet that burned my knees when I rolled onto it quick. It's also topper with the sheet part of it. So not just the memory foam top part like some of them.
code for discount is LK5YNGB9, I think it works with twin and twin xl only apparently. 70% also shows as applicable on the amazon page. Corrected post since it only works on these two sizes.
