I had an outside prescription, and I went to the Oakland location to look at glasses. I found a pair I liked and had them calculate the total cost with my insurance. They were more expensive than other places I had looked, so I told them I wasn't going to buy them and to drop the authorization on my insurance.
Two weeks later I went to a different retailer and decided to purchase my glasses there. When they went to enter my insurance information, the hold from 3 Guys was still there. I had to call Three Guys and tell them to drop the hold immediately because I was about to purchase glasses from another store. The guy on the phone was completely rude throughout the entire process. He literally said "Whatever you're paying for them, I can get them for you cheaper." Really?!? 3 Guys told me the total cost would be around $260. I got the exact same frames with the same lenses for $90 elsewhere. I highly doubt they could have come down to beat that price.
