I bought comic book boards on Amazon; I bought a 500 pack for $43.74. That comes out to about 9 cents per board. They measure 6.75 x 10.5.
$4.60 for a sheet that's 24x36...well the sizes don't come out the same but if I went for a 12x7(ish) board, which is about the closest size that would come out evenly, that means 10 boards per sheet for a cost of 46 cents per board.
So unless I'm doing math wrong, corrugated is a lot more expensive, and then there's all the work of cutting the boards. BUT I bet your corrugated will last a lot longer than my comic book boards and the boards I bought are only acid-free on one side so they're not really great for truly long-term storage. But your corrugated plastic will be entirely acid-free. So there's some benefits to the corrugated, but for what I need (about a thousand boards!), I'm sticking with the cheapies!
