They sell instant potato flakes. I think they are cheaper at Sam's for the Idahoan brand.
They sell bulk Idahoan instant flaked potatoes in both the red and white variety packaged in the large milk carton institutional sizes. Stick with the brand name Idahoan ... mixed with milk, butter and pepper (and we used a bit of chicken bullion rather than salt) and our customers cannot tell them from peeled potatoes. You can always throw in leftover baked potatoes or boil a new pot of peeled potatoes for a chunkier effect but it's not needed.
Will they sell the instant ones but I'm not sure if they sell the ones that are already pre-packaged in made already you might have to call the store about that
