Anyway, if I were wanting to take advantage of that sale but needed an E or wider, I'd simply go to a brick and mortar JAB and ask the manager if he could order one in at that price. All they can say is no. And as noted above, they've offered wide sizes in the not too distant past, eg last year.
A year or two ago during the big Nordstrom sale, they had some colors of the Nuemok at a huge discount. I asked the department manager if he could order me the (not on sale) snuff suede at the sale price. It was going to have to be drop shipped anyway. He said "sure." It was like free money to his store.
