toptiergas.com has absolutely no info regarding WHO they are...

I used register.com to see who owns the site:

National Products Group
PO Box 3475
Tulsa, OK

The administrative contact's e-mail address is an AOL e-mail account -- interesting.

The phone number given for the administrative contact is (918) 836-8551 -- google says that that phone number belongs to

QuikTrip
901 N Mingo Rd.
Tulsa, OK

QuikTrip's website -- http://www.quiktrip.com/default.asp -- shows the very same PO Box at the very bottom of the page.

Why does toptiergas.com make absolutely no mention that it is affiliated with a chain of convenience stores? QuikTrip's website does have a link to toptiergas.com ( http://www.quiktrip.com/gasoline/toptier.asp ), but I find it interesting that toptiergas.com has no backlink to it's parent site.
