Do you support GE & Price checker after free trade ?

I like the ge, beats hours standing outside fally trying to buy nats at a good price :/ The price checker is helpful but it's going to work against us when exploiting the chicken farmers etc. Used to camp outside the lumby chicken yard buying thousands of feathers for 3-5 gp each then selling them to members for 10-12 gp each. <--- That was when I was lvl 70 lolz.
