Roger,
I have bought from CDI a few times. His shipping charges on the website are only estimates. The actual charges are always less than the original estimate. The last time I ordered a bunch of C9 LED retros and some other stuff, the shipping estimate was around $120 but the actual shipping charges were only $60. Call Paul or Lee and they can probably give you a true shipping cost. They are really nice people to deal with.
Hope this helps.
John
