You sell 28 at a time, and you can probably do about 3 trips per minute. 28 x 3 = 84 per minute It really is quick to sell, I wait until I've got 100-200 and then it takes about 5 mins to get to Grand Tree, sell them, and then come back. using a more conservative estimate [2 trips a monute] that's about 895k every 18 minutes - that's pretty damn awesome! someone please correct me if i'm wrong 'cause that does seem like alot to me.
