It's sad, but I remember the big introduction of the glorious GE. As an f2per at the time, it was very difficult to be able to buy things in bulk unless you struck a great amount of luck in w1 or at Varrock East, because forums were 100% p2p (something which even then, I supported). And trying to sell things in bulk? Forget it. When coupled with the trade restrictions, it made it really hard to trade the way we used to. Buying in bulk on discount? Nup. It's definitely been a good thing, but it had it's downfalls. Long gone are the days of loyal buyers/sellers to particular people. :(
