I receive a 1099-Misc with income in Box 3 from manufacturers' that I sell for in my regular job. Can I deduct expenses against this income? Ex.business gifts, meals,etc.

I am in sales and receive a 1099-MISC from some manufacturer's that is reported in Box 3.  I have always reported it as "other income" but some of my coworkers said they claim it on Schedule C and deduct expenses for meals, business gifts, etc.  Can it be reported that way?
