Have to share this related story. I recently got a new prescription and the glasses salesman at my optometrist said that my insurance is super generous and willing to pay upto $200 every year for new glasses, so I should definitely get a pair before the end of the year. So I looked around and picked a frame I liked. The salesman measured my PD and started offering me options on the lenses. Coat this, photo reflect that. I said no to every option that was offered since I know those will rack up the cost. In the end the salesman added up all the costs and said that the total will be $230. I was like that's great so I only have to pay $30 for them. But the salesman was like I already deducted your insurance payment in the calculation, the actual cost is $430 of which $230 you will have to pay. After hearing that, my eyes opened so wide that 20/20 vision was restored in them.
