Advertising expense taxation?

[Nate Jackson]

Every week I partner with a new charity and design cool apparel for that charity on my website. The charity advertises their partnership with me on their Facebook and twitter. That leads people to my website and I give $7 to the charity for every item I sale.

My question is this. I give $7 for every shirt and I only make 6.75 profit on each shirt. I am not technically losing money because I sale many shirts each week.

Will I get audited if I have 91k in advertising expense and only 87k in profits. By glance will an IRS agent think I am losing money and audit me? I am actually making 87k which is great money.
