Cheapest Zeiss Replacement Lenses in Houston

Having worn prescription eyeglasses my whole life, I have plenty of frames I like, but want to replace the lenses for a new RX.

I got one pair swapped at Costco which charges a flat $150 for Hoya lenses with transitions + ar and all of the other basic coatings.

I also got a pair swapped out at Perfect Vision on Richmond for Zeiss digital 750 lenses, which they charge an exorbitant $591 for ($169 for the lens + $89 Poly + $169 AR + $139 Transitions + $25 Fee). I'm super annoyed with them because they misquoted their prices to me when I dropped the glasses off and initially paid them, and then demanded I pay the difference to get my glasses back. Avoid them.

So before I send the rest of glasses over to Costco for their Hoya lenses, I was wondering if anyone in Houston swaps out Zeiss lenses for a reasonable fee?
