Gap is having a 40% off sale on everything today, and it's working on the PrimaLoft Luxe puffer coats, which are already marked down from $98 to $58. I'm pretty sure these are the ones that were formerly called the Warmest coats.
I got one for under $38 with tax. And 7-9 day shipping was still free because the coat is originally more than $50.

I never bought one last year because I didn't see a good sales price on it. But we loved the one we had two or three years ago.
