sure why not. Just don't charge for profit and make sure to have free stuff also for those people who cannot afford it (i.e. the cheap 1.50 dollar version of Holliness of God, sermon CDs, Tracts, copies of Sinner's in the Hands of the Angry God, ect...). But I would be careful because my former church had a problem of people (professing Christians) stealing books and doing it in the name of "tools for sanctification and its wrong to charge" even though my pastor sold under cost.
