1-800-Contacts is a good place to order contacts from. You must have a valid prescription to order, but it is a lot more convenient that going to the doctors office. If you order online and your order is over $50, you get free shipping. I added contact lens solution to my order to make it over $50 for free shipping. It cost less than the contacts plus shipping. The contacts came within a few days with the cheapest shipping. They will exchange contacts if your prescription changes.
