Moab by Legion Paper has some extra paper from a special order they made for customer. It's a 350gsm version Moab Entrada Bright in 24x36" sheets that they are selling for $1/sheet in quantities of 250 or more. This is an experimental weight of Entrada that will not be made again. No returns. With the unusually heavy 350gsm weight, this sounds like an unusually sweet deal to me if you like 24x36" sheets.
