Looks pretty legit, this is the main site I found from Google:
http://www.ushopwireless.com/wireles...ndex.php?oc=SS
It does seem a little too good to be true to be honest though, a $500 blackberry and you only have to be locked into a contract for just 1 year seems a little too good but from the looks of a few searches done on Venicom they do seem legit.
PS: If you do buy this offer, do us a favour and don't buy from the spammers refcode, use the direct site. Don't encourage spammers
