Vendor Bags

Until Cataclysm Comes out I have cut down my on what I sell by about 75%, so I'm not making as much as I'm use to. So I started experimenting with stuff to see If there are some ways to make some extra gold. Well I found a way to make some extra gold regularly. Vendor bags sold by the innkeeper at hellfire peninsula, wich are 20-slot bags for professions. They sell for about 14 gold from the vendor and I have been able to sell them for 40 gold on the AH, for about 4 times the price I paid for them. I post them for 40g because on my server frostweave bags, the 20-slot normal bags, sell for about 45g on average on my server. So I sell the 20-slot profession bags for a little bit cheaper than they can buy an all purpose bag. I didn't think they would sell since they could spend a little bit more for a way more useful bag. But they did and I didn't have to sell my bags for less.
