Most online purchasing requires a certain amount of intuition. Unfortunately, some of us are no longer skilled in that area. What you want to do can most likely be done even though it may not seem like it at first, but just keep pushing buttons. EZContacts will not spend your money without a warning. During the process your order will be displayed along with an "edit" and "cancel" option. I wore these options out before I got it right. EZContacts may not be the least expensive online contacts retailer, but of the five I tried they were the most honest. Don't be discouraged when you come to a dead end. Software developers turn to beta testers to verify there efforts, but beta testers are often "power users" not the purchasing public. Hang in there, and enjoy the process.
