Just want to reiterate that if you find that the link in any shop instructions takes you to a site that does not look like RSG, it very well might not be.  It's nice of them to help out other companies in filling shops, but not at 50% of the original fee.  I don't know if this is a common occurrence or a one-time thing, but just be careful.
