Does anyone know if 49ersofficialonline.com is a authentic website?

Sorry that 3 week old site is registered to a fake Las Vegas address, but a +86 Chinese phone number through a Hong Kong registrar, so no they are unlicensed Chinese knockoffs that the authorities treat like fake handbags. Funny the other site in the same file server is ravensnflprostore.com registered on the same day.

Got that info with a domain name whois info look up:

You didn't say if you received it yet. Those are expensive fakes capitalizing in the Superbowl craze.

any time there's no identifying phone# or address in the Contact Us page, it is highly suspect.
