Not too long ago, I blogged about how I saved over $400 dollars with SnipSnap at Lenscrafters. Eyeglasses are one of those things you should never, ever even think about buying without a coupon. The unfortunate things is that most people end up buying eyeglasses in a hurry, when a pair is lost or broken, and they don’t take the time to save. SnipSnap solves that problem at Lenscrafters, Pearle Vision, America’s Best and more.

Warby Parker is an amazing startup offering sleek, vintage inspired prescription eye wear for less than $100 a pair. Best part: for every pair of glasses purchased, Warby Parker provides a pair of glasses to someone in need by funding global non-profit partners like VisionSpring. Did you know that 15% of the world’s population can’t learn or work properly because they can’t afford prescription eye wear? That’s a billion people who can’t live up to their potential. Vision correction increases a person’s productivity and income by 20%. Think about what the world could do if only everyone were able to see clearly.

It’s kind of incredible that one company can make glasses affordable to the poor and the not-so-poor. (Glasses are way too expensive for almost everybody.) So it’s beyond amazing that Warby Parker has teamed up with social gift-giving apps like Wrapp and Just Because to offer even more savings to loyal and new Warby customers.

Unless you’re near a select Warby showroom, you’ll have to purchase a pair of Warby Parker’s online. They’ll send you up to five frames to try on for free, and then you’ll submit your prescription with your order. Warby’s customer service is phenomenal (they’ll ever answer your tweets with personalized YouTube videos). And they’ll do almost anything to make sure you’re happy with your glasses. Want to order a pair of Warby Parkers online? Ask one of your friends to send you a free Warby Parker gift card from Wrapp (offers are worth $10-$20 depending on the day and the person).

Or you could ask for a $1 gift card good for $20 off Warby Parker using Just Because.

$75 = a pair of glasses for you and a pair of glasses for someone who desperately needs them. And a win win turns into a win win win with mobile coupons. It doesn’t get any better than that.

Bonus: Warby Parker is currently taking its showroom on the road with the Warby Parker Class Trip bus tour nationwide. Stop by when Warby visits your city to find your perfect pair of glasses!

I visited the Warby school bus in Philadelphia yesterday and fell in love with these frames!

(I also had fun with the free Class Trip photo booth.)
