Not the original commenter, but my wife and I have had several pairs from http://zennioptical.com and been very happy with them.

(And speaking just for myself, I'd prefer not going through Amazon if it can reasonably be avoided.)

I love Zenni. I buy glasses from them quite a bit just for a change of look. I think the cheapest I've been able to buy them for so far is about $10.

Seconding the Zenni recommendation.
