I didnt read what every1 wrote but wut Hccmike says is the best way to do this. I've done many times w/ my friend and 2 ppl is the best combo. use Hccmike's idea about sending to urself thru AH. wen all 8 slots r filled up go to ur MH and just check the delivery box. (NOTE: you do not have to take anything out yet. simply by checking the delivery box will open up those 8 spaces in the NPC sender, but this only works once, because from now on you will have to take stuff out of the box to send stuff thru the NPC. don't know why but it only works once.) so after this u can have 16 clocks in ur MH. then switch palces w/ ur friend i.e. u kill BB and he sends clocks to his MH, and then gets 16 of those. (NOTE:have ur friend in the zone that is closer to BB spawn point, i think its mines, not too familiar w/ bastok, but this is because it is shorter run from zone to AH.)
one more thing. have both of u in south gusty, but the person delivering the clocks, set them as quartermaster. Party>>Distribution>>Quartermaster. this way he receives all items if u r in same zone. then he just zones to mines and runs 10 feet to the AH. (NOTE: wen u and ur friend switch places remember to switch quartermaster.)
then wen u r done just turn in all the clocks, running from MH to Malene.
Me and my friend got into such a 'groove' that in 2hr.s(take into account the time to get into the 'groove', which was prolly bout half hour) that at the end of 2hrs, profit, not including deductions for the fish were 30k each since we split the money, so 60k all together in 2hrs.
Now on my server Bismarck, the AH fish in basty r only 700-800 and we split that cost too so we only really spent like 350-400 gil a stack, and in the end made a profit of 30k each, total cost for the fish alltogether, i dont remember, but the numbers r all there, you do the math, 60k 700-800 gil a stack, just calculate how many stacks and gil we spent. veyr profitable.
