1. Refer a Friend

It's easy to see a brighter world when savings can be found just by telling a friend. Lens.com's Refer a Friend program rewards customers with $10 savings each time their friend places an order. This gift is double-sided, too. The referred friend also receives a $10 discount off his or her first order. The best part of the program? There are no caps on the savings potential.

2. Receive Coupon Codes

Once a shopper is in the Lens.com system, coupon codes are sure to follow. The company stores emails solely for the purpose of spam-free bliss. The codes arrive free of charge in members' inboxes, ready to take charge of discounting the fees when the next shopping trip rolls around. For clarity, membership is also free.
