Get 6 gold. Look at the AH. On most servers, there will be that one ****ing idiot who sells a stack of 20 heavy netherweave bandages on the AH for 5g, when they vendor for a little over 6g.
Rinse and repeat till that idiot makes some more heavy neatherweave bandages, since he thinks their a hot item and selling fast.
PS - This might be the same on all servers, but meh.
EDIT - Yes this is a poor attempt at a post
Edit again - This is also the same for Golden Pearls, they vendor for 1g and idiots sell them for less.
