Coastal (also known as Coastal Contacts) offers a select pair of glasses with lenses
via coupon code "FIRSTPAIRFREE". (Scroll down and click the "Get Your First Pair of Glasses Free!" banner to find eligible styles.) That's tied with last month's mention as one of the best such offers we've seen from Coastal. Shipping starts at around $8
. (Note that a mandatory shipping insurance fee, which varies based on the value of the frames, will also be added.) Several terms and conditions apply.
Note: If you have already received a free pair of glasses via a similar promotion from Coastal Contacts, you are not eligible.
