I use 1800contacts.com. You do need an up to date prescription but the site will call your eye doc and verify for you. Free shipping too when you order a years supply and there typically is a rebate.
I normally use 1800contacts.com... they will verify with your eye care provider that you have a current prescription on file... Contact prescriptions are only good for 1 year from your date of exam.
We've also ordered many times thru 1800Contacts with no complaints! You just have to check around, it just depends on the type of lenses you wear, if you can get rebates etc
Visiondirect.com
I can usually find good coupon codes for this site also, and get a great deal. I compared the prices to 1800contacts last time and vision direct was a better deal
