Tanner Polk of Amarillo believes he has a servant’s personality. That, he said, is why he began a business called Store to Your Door four months ago. “It’s a community-based service,” he said. “What if you could just make a phone call and, in a set period of time, anything you need, it could be right at your door?” Polk, 30, provides personalized grocery and package shopping in the Amarillo area.
