Recently I purchased a CH-46E/F from http://www.scalehobbyist.com/index.php
I based the choice between the two Hobby Boss kits and wanted the one with the US Navy decals. Well, their web site had the declas switched between the 2 different models and I purchased the wrong kit. I notified the webmaster and they saw the problem and he emailed back and said I could get the decals I wanted no probelm. I let it end at that point and never replied. Lo and behold today the HB CH-46D kit showed up in the mail FREE!!
If you have not checked out their web site they have very good prices on their kits and I have been using them for about 2 years now.
