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. Assuming you've actually got 895 Giant Frog Legs then I think 18mins is about right. The hard bit is getting the Frog Legs (not many sellers). But it can be used to make money over time like MTK. Jsut leave the buying in the exchange then come back each week and sell your profits.
