If you have a LW, it may be worthwhile to check the prices on vs . On my realm I can buy 5 scraps for roughly 1/2 the price of a leather on the AH. Currently I'm using it to level my LW, but it would be a good source of flipping.

Just something to keep an eye on. This is likely to those who have a Skinning/Other farmer toon, and so when they get the scraps they are unable to convert them over to the usable leather.
