I've bought stuff from all 3 before. Zenni is the one that I finally figured out how to order for my PD correctly, but there are some caveats.

1) See this twitter https://twitter.com/troyd/status/560089054356574209 - My zenni specific email was spammed. They either sold my email or they were hacked. I don't know what the cause, but I would not give them anything valuable including only using PayPal with them.

2) Their anti-reflective coating is not as good what I get from local optometry. My pictures tend to have this greenish tint, and I paid for the best thing you can get from them.

That said, I was able to get $8 glasses that worked and I can see perfectly using them. If I need cheap glasses, I know where to go.
