I saw a site advertised on facebook for Oakely sunglasses. It isLog In. They have glasses that normally retail for 165 dollars for 24.99. Supposedly sharing the link for the site nets you another 1.00 off. I am not really into designer sun glasses at all, however, for that price..even I might go for them. They would also make a great gift.
I would be on the lookout for fakes. There is a big business selling fakes passing them off as some bargain. In that case, of course, you're not really getting a deal.
