This is a great service. I ordered my contacts (they are fairly new to the market and a bit pricey) and felt I was getting a good deal. I received a call from Deliver Contacts letting me know that I could save even more money if I purchased the 90-day boxes. They adjusted my order and refunded me the difference. I'm not sure I've ever had that happen before! Most companies don't go out of their way to tell you how to save money on their products. I am now a proud customer of Deliver Contacts and look forward to working with them again for my reorder! Highly recommend.
