You don't say this about many stores: My experiences with ReadingGlasses.com have always been excellent. I've been buying reading glasses from them for more than three years -- mostly folding and "tubular" pairs to start, and now all sorts of pairs for my car, work, briefcase, etc. Their quality is good as are their prices. And you know what, so is their customer service. I always know that if I ask a question, Peggy will give me a call (in her cheery Dallas twang) or drop me a note and follow up.
When you find a company like this, you support them and do business with them for a long time. They seem to appreciate you as a customer as much as you appreciate them for their good service.
