Meta Ray-Bans for 20% off is a great deal on one of my favorite products

The Meta Ray-Ban Smart Glasses give you nearly the same audio quality as AirPods, a fast camera, and a hands-free AI assistant. This product rarely gets discounted, so this is an ideal time to take advantage.

Among the most popular tech products of the last year, the Meta Ray-Ban smart glasses have been the surprise hit. Amazon is currently offering the version with the classic black frames for $239 (20% off the $299 retail price). 

This is an especially excellent deal when you consider that many styles of the Meta Ray-Bans were often out of stock for much of the first half of last year -- and the smart glasses have rarely been discounted. A lot of the appeal is the fact that they look just like normal Ray-Bans, and you can even replace the lenses with your own glasses prescription. 

The caveat to keep in mind here ...
