Went to our local O'Reilly's to ask about replacing a headlight, which on the website it states: Wiper Blade & Bulb Installation - Free
Our Parts Professionals will install wiper blades and replacement bulbs free of charge (with purchase of wiper blades or bulbs). Whether you've bought front or rear wipers (or both), headlights or tail lights, we'd be happy to install them for you.
They refused. Will not go back there again.
