Advertising is used by virtually every business to build sales volume.
Large corporations have entire departments devoted to such activity. It's true that almost every business, professional, fraternal group, school, gift shop, retail store, advertising agency and special events promoter purchase and use 'advertising specialities'. From the one man barber to the group of dentists to the large corporation and every other business in your area is likely going to purchase one or more 'advertising specialities' this coming year. In this field, the opportunity for profit is limited only by your imagination and intelligent effort. BUT they go on constantly in every area and the retailer often will contract for hoopla and goodies to draw-in a crowd.
