We serve two distinct customer bases - the professional (installer) customers who provide auto repair services to their customers (DIFM - do it for me), and retail "walk-in" customers (DIY - do it yourself). Our dual-market strategy continues to differentiate us from the competition and is a major factor in our ongoing success. Depending on a store's professional versus retail customer mix, more than 95 percent of our locations have team members dedicated to our professional customers, offering them separate counters, phone lines, and a delivery fleet that totals 18,455 vehicles. We also have a professional sales team, consisting of territory sales managers and in-store sales specialists, responsible for calling on our professional customers and building sound business partnerships to ensure O'Reilly is the First Call for their auto parts needs.
