Designer Optics has several discounts running right now, with the Back to School Sale delivering 7% off sitewide as the main promotion. Depending on what you're buying and how much you're spending, a different offer might actually save you more money at checkout.
Buying frames, sunglasses, or general eyewear under $100: The Back to School Sale's 7% off sitewide is your best bet for most purchases in this range. On a $50 order, you'll save $3.50; on a $100 order, you'll save $7. This offer covers everything on the site.
Buying prescription lenses: If you're adding prescription lenses to your order, the 15% Off Prescription Lenses deal will outperform the Back to School Sale. On a $100 prescription lens order, that's $15 in savings versus $7 from the sitewide discount. This is the strongest percentage offer available and applies specifically to lens purchases.
Building a larger basket with mixed items: The 15% Off Your Purchase offer rivals the Back to School Sale on larger orders. At $100 or more, 15% starts to deliver genuine savings; on a $200 order, you'd save $30 instead of $14. Check which of these two applies to your specific cart at checkout and go with whichever number is higher.
First time or returning customer: If you haven't already signed up, the Newsletter signup offer can unlock special discounts and promotions tailored to your shopping profile. This is worth doing before you check out, since promotional codes sent to newsletter subscribers often beat the public deals listed here.
Buying designer eyewear: The Up to 50% Off Designer Eyewear promotion applies to select premium frames. If your chosen frames are included, this will beat every other option on the page by a wide margin.
Beauty products: The Beauty Products Starting at $495.34 offer appears to be a product promotion rather than a percentage or dollar discount, so compare the final price against other offers before buying.
Remember that retail sites typically allow only one offer per transaction, so you'll need to compare the dollar amount each one saves on your specific basket and apply whichever produces the larger saving.
