Crown and Calibur?

Has anyone heard of/used this company before? It popped up on my FB feed, and is definitely seems to be one of those "too good to be true" kinda things. I went to check it out, but they asked for an email right away. Anyone had an experience? Thanks.

I have not heard of them. I looked at the site (made up an email address to get that stupid pop-up off the screen) and they seem to have good prices and a decent guarantee. Of course the guarantee is only as good as the vendor.
