Is having 'Your Own Background Check' along with Resume something that will help you, as the ad says?

When going for a job, i have seen it advertised for a company to do your own state-wide background check for you. I am tempted to do this. It says: If an employer is thinking of hiring you, having your own background check results as run by that company will save them the time of doing so, and put you at an edge to get hired.

Is this true? I am thinking of going this route. Any insight here, and ways to best present yourself to employers (from Fast Food to upscale Fast Food to Customer Service, any employer general things?) Thanks

don't waste your time, they will do their own background check because yours could be a forgery

I agree. If they're worth a damn, they will have the money to pay for their own background checks, and do it as a standard practice anyways.

Only reason why I would buy a bg check is if I was wondering what was on there in the first place. Ever been fired?
