Make 5 grand 'simply by sitting infront of your pc' Sounds too good to be true aye? BECAUSE IT IS! Very few people buy diablo 2 stuff, and even fewer buy it frequently.
Its not a '5 grand a month' business, im sure of it. I could see 2-3 grand on a good month, or if a new item came out, but its not something to rely upon for money. I'd rather get a white collar secure job than duping bs.
Besides how are you gonna pick up chicks telling them you play a game for a living?
