When my husband & I were doing family crusades, we were told if we didn't sell product in the back, we were losing half our potential for income. As an evangelist, this is important.Officials probably don't have that worry, but if you've written a book, take a moment to promote it and encourage people to stop by. A lot of times they'll offer a deal if you buy more or one price for all of it. I don't mind preachers mentioning it, but tarrying there too long can turn folks off More of Him...less of me.twitter.com/camiracle77www.facebook.com/profile.php?id=691241499&ref=name
