Not a single dime was spent on filming or producing the movie. The brothers' only expense was hotels, food and taxis which they would have incurred had they been on vacation instead of shooting a film.
The movie climbed as high as #43 in iTunes Top 100 Movie chart and has grossed over $200,000 in profits. There was no expensive marketing budget, either. Most sales were generated by word of mouth or circulation on social networks.

Isn't that like saying I haven't spent money on an entertainment center since it's the same amount of money I would've spent if I had spent it on booze instead?
