Simple Ways to Save at DIFF Eyewear

Saving money on your next pair of cool sunglasses or blue light glasses is easier than you think. The first thing you should always do is check for a promo code box at checkout. Before you click "buy," take a second to look for it and type in a code—it could save you a nice chunk of change. Another simple trick is to sign up for their email list. Just pop your email in the box on their website, and they'll send you a welcome discount right away to use on your first order.

Best Times to Shop

If you can be a little patient, you can score even bigger deals. DIFF has great sales during major holidays. Keep an eye out around:

• Black Friday and Cyber Monday: This is usually their biggest sale event of the year.
• Memorial Day, Fourth of July, and Labor Day: They often have site-wide sales for these summer holidays.
• End-of-Season Sales: When they need to clear out inventory, you can find past styles at a steep discount.

Pro tip: If you see something you like that's not on sale
