Nearly Endless Money
Go to the majiin buu saga and then to the 'Two Buus' scenario. Dont fight the evil buu, go to the free event at the mountain road. You will have to kill a lvl.226 Yamcha. If you have already gotten the gold membership card for shops, this should be an easy victory. You can choose from hurcule or fat buu.
(I think the choice is obviouse...)
Kill him and you will get 1,000,000zeni along with the Fox Mask item which is used to unlock grandpa gohan.
Do this four or five times and you have enough money to last a long time.
