Please note that this size will frequently require folding across the 24" axis for shipping in 12" boxes or to be shipped separately due to not nesting well with the rest of the order. The price is slightly higher to absorb some of the often extra effort or cost to ship. If you do not need a continuous width of 24" then two pieces of 12" wide might is an option to consider to save a couple bucks.
If your application requires that the material not be folded please email before your order or make a note in the comments at check out.
