You can get credit through Coastal’s referral link, but heads up: the credit only kicks in after their order actually ships. Also, your friend usually can’t stack your link with sitewide BOGO codes. Honestly, check if the standard new customer coupon beats the referral discount before you bother sending it.

Just fill your cart and hit step 3 of checkout to see what's currently active. They take standard cards and PayPal, but you can also run FSA or HSA cards directly if they have a Visa or Mastercard logo. If your vision insurance doesn't direct-bill, just download the itemized receipt after to file manually.

Coastal doesn’t really do sitewide sales anymore. You basically have to dig through the clearance page and filter by your frame size. Heads up at checkout, though: the frames look dirt cheap until you add high-index lenses or anti-glare, which destroys the savings. Try tossing in a new-customer code to offset it.

Just toss a burner email into the newsletter pop-up for the 20% off code. Heads up though, it usually doesn't stack if they’re already running a BOGO frame promo, and brand names like Ray-Ban are excluded. Paste the code into the "Promotion Code" field right before payment. Saves a decent chunk on lenses.
