These guys are master spammers. Once goggles4u.com get your email goggles4u.com will flood your inbox with special offers just for you (and the entire world). There will be a link to unsubscribe, but it won't work unless you're using internet explorer. goggles4u.com don't offer any other way to get off their mailing list. You can complain online to goggles4u.com, but that only gets you automatic replies back with no solution. There are other online companies selling glasses that won't spam you so whatever you do - don't give these people your email address! (or if you want to really annoy a boss/coworker/neighbor - sign goggles4u.com up!).
