I am planning on buying a second hand computer monitor off Craigslist. I would use it for my work as a contractor. What steps should I take to be able to write it off as a business expense? I can take a screen shot of the website. I was thinking of asking for a receipt but hypothetically if it just says the amount I paid, that can be forge very easily.
Bit of an aside, why are people so reluctant to buy things of second hand websites like Craigslist? People go crazy over a deal in a store but these prices can be way cheaper. The box for this monitor hasn't been opened so I'm confident it's new.
