Rat Trap Delivery Truck Bug

If you are at max IGC and have a decent bonus percentage, then skip RTTs and bloodmobiles. Buy a Krusty Oil Rig. Collect bonuts. Sale Oil Rig. Rinse and repeat. The lags and Bart screens don't factor in as much. I stumbled upon this earlier this year and it completely changed the way I farm for donuts. Each morning I hit the sky finger (wait for it to slowly collect all XP and then slowly go about collecting donuts) and then i buy/sale an Oil Rig. Collect those donuts and go about my day. The whole process is so much faster.
