Marketers who use promotional products as part of their advertising mix give high marks for these items as effective, budget-friendly ways to connect with customers, according to a 2009 study conducted for Promotional Products Association International. In a survey of more than 1,000 participants, promo products outranked other mainstream media such as newspapers, television and Internet, for their ability to promote repeat business, be flexible within budgets, and achieve long-term recall. The survey was run by researchers at Louisiana State University and Glenrich Business Studies.
