Target, Staples, Dollar General, other retailers lure in teachers with back-to-school discounts By Daniella Genovese retailers are trying to lure in teachers with competing discounts ahead of the upcoming school year. The main competitors are Target, Kohls, Staples and Dollar General – all of which are trying to capitalize on the back-to-school shopping season. For its fourth year, Target featured its Teacher Prep event, offering teachers a one-time discount of 15% off select classroom supplies if they join the company's loyalty program, Target Circle. The discount applies to all K-12 teachers, homeschool teachers, teachers working at daycare centers and early childhood learning centers, university or college professors, and vocational/trade/technical school teachers. However, it only applies through July 31.
