Never seen a worse tip.
Easy money was jumping around New Haven in a circuit opening the 7 or so crates that are there, selling everything you find, then popping back to the main menu and doing it over again. Dunno if the new patches have changed the drops for the worse, but you can easily rack up more cash than the counter can display this way on play through 2.
Course there's other ways, but I figure that's enough for anyone coming to this topic not to walk away disappointed.
Well, every1's way of money-making on borderlands varies sumhow, like blueman likes to blow the crap out of people, u like to farm for money, and i like to do the objectives, occasionally going thru the 7-chest circuit at new haven.
And I think the easiest way to make oney is to go thru crimson fastness killing everything, saving, and then coming back selling all the loot from the last runthru. easy exp and pretty decent money
