Things I don't understand

There is a laser-eye-surgery outfit here in San Diego—I am sure that it just part of a chain—that is currently running a two-for-one special. That's right: two eyes for the price of one. This I do not understand. If there's one place that I don't want crazy cut-rate prices and half-price specials and coupons, it is when someone is pointing a laser at my eyes and probably royally ruining my sight. It is not like I will be needing those eyes later.
