Wow TIFOSI is amazing
Their warranty states that there is a $15 fee to send in defective sunglasses to get a replacement.
It also states that if the ones you are sending in are no longer in production, they can substitute a current model.
Now here is what happened when I used it:
I sent in a years-old pair that had begun cracking at the corners of the lenses. This pair had the conventional type of frame, and was no longer being produced. Upon receiving it, they sent me an email stating that since it was not a current model, instead of sending a replacement, they were providing a 50% discount coupon code for . They did not put the $15 charge on my CC.
Wow that's amazing, what have I been missing, I gotta get TOFOSI.
