Clicked an ad through Facebook and added what i wanted to my cart, but just kept loading, obviously stuck, when I tried multiple methods to make an account/sign in. So I had to go to the url via browser instead so I could make an account and sign in, but I had to re enter my prescription and preferences and the frames were not on sale on the regular site, (only on sale through FB ad?). Eventually I was able to get the sale price and also log in, but took a lot time to figure it out.
