We had been to a well known Optical store, whose name starts with O and ends with M with two letters in between, for a quote. We were quoted 749 dollars for the frame and lenses while Blink quoted us 629. Same frame plus 167 lenses(Hoya). Service was excellent. ended up out of pocket 170 dollars after massive discounts and rebate while the other shop quoted I would be out of pocket 410. It was a no brainer.
The same with a pair of Sunglasses, to have prescription lenses. We would have been out of pocket 280 while at blink it was 50.
Both are HBA Member first and provide the same lenses and frames.
