I got there through Duke's site, but they don't make it easy to find. You have to log in to your acct. and look under "For your Home." There's an option for "Save Energy and Money." Click that. Under "Get Started" there's a link to "Pay less for energy saving bulbs." Click that. Then there's a link for "Visit our energy efficient lighting website for more information." Click that. Then click on the "Local Retailers" link. Off to the right, there's a link that says, "For online bulb purchases visit:" And it's the same link given by the OP. Good grief but they really don't want you to get there.
