For a limited time Amazon is selling the Echo Show for $80 off!
That makes it less than the regular cost of the first generation Echo. Personally, I think this should eventually be the regular price for the Echo Show, but since it currently has no competition, Amazon can charge what they want for it.
Currently, Amazon has the entire product line on sale with pretty deep discounts on all of their devices, but the $80 off Echo Show sale is by far the biggest discount available.
