One thing that any Prepper needs is extra eyeglasses for the whole family or group. That can run hundreds of thousands of dollars. However, there is a little known site called Eyebuydirect.com that has hundreds of styles of glasses starting at $6.95. I will say that I have personally used this site for years now and have a nice selection of glasses stocked up.
When ever I want a new pair of glasses I just login to the site, and select the frames that I like and hit buy and in less than 2 weeks they are on my front door step. What is really awesome is that they are made in Ontario, Ca and they come with a hard case, and cleaning cloth.
Having these backup glasses have saved my butt more than once, because my main set have lost screws or what have you. So here is 15% off all orders at EyeBuyDirect.com! Code: couponology15 to help you and your family get started.
You will need to know a few things however, which you can easily obtain from your eye doctor. You will need to know your prescription, and pupil distance. This is good info to have on hand anyways. If you do not have medical insurance that covers vision the cheapest route is to go to Wal-Mart Vision Center as they normally only charge about $50 for the exam and you do not need to purchase their glasses or frames. So if you are paying out of pocket then you may want to try this method. The other thing is to take advantage of their BOGO sales during Back to School Days, many times you can get 2 pairs of glasses for less than $120.
