Just saw that 39DollarGlasses has a coupon code for St Patricks Day. The discount is valid on ALL glasses on an order giving you $15 dollars off each pair. Pretty nice discount if you ask OpticalOwl. All you need to do is use – LUCKY15 – at checkout and you are good. The discount should apply at least.
Only caveat is that the St Patricks Day discount is not valid on contact lens orders. The 39DollarGlasses coupon code expires March 18th. Better hurry if use it.
