So, yep - this $300 pair of polarised shades are $2. 

Whats the catch? - They have a tiny fracture in the upper corner of the lens. It's not dangerous and it ain't in your DIRECT line of vision. 

If you're fussy about $2 sunglasses - please don't buy them. Just to be clear - these are seconds (unworn)...but seconds. 

So if you'd dig a $300 pair of backup shades for the car and or boat....buy them here
