Is PB Distribution Online a legitimate site?

Have any of you ever purchased software from a website pb distribution online? ( a href="http://www.pbdistributiononline.com/servlet/StoreFront" rel="nofollow"http://www.pbdistributiononline.com/serv…/a ) They have really good prices on Microsoft Office, but under the principle of "if it looks too goo to be true" I'm a little wary. Any information on the website would be appreciated!
