So this is not my method but I stumbled upon a ton of bots buying Kebabs in Al-kharid. Proof is attached somewhere...
---------------------
Kebab = 1 GP
GE Price = 30 GP
30 x 27 = 810 GP
One inventory takes a 1.5 minutes, so 810 x 45 = 36K an hour
This guy is running 5 accounts so 36K times 5 = 180K an hour
Imagine running 10 accounts lol, that's 360K an hour. In about 10 hours you get 3.6mil...
People run farms of up to 50 accounts so in 10 hours they net 36mil...
Cost to setup is basically zero
You are welcome peeps
EDIT: I JUST SOLD ONE KEBAB AND IT SOLD ASAP LOL!!! PROOF IS BELOW
