Customer testimonials
“Keep up the good work. Your personal customer service is great. It was great being so well informed about the status of my order.”
Brian - Waco, TX
“I wish that more business, on-line or store front, had as good a grasp on customer service as the AltE Store does. It was a pleasure from the start, e-mail, phone calls and even a major problem. All were very pleasant, friendly and positive. I do hope you keep up the wonderful business philosophy you currently have.”
Paul - Covington, LA
