I may also be missing something, but is this not just a site advertising that they are selling you Bee protection.
I don't feel that somebody saying they are going to give you plans for free and then you have to register with a lot of info that is compulsory before you download the plans.
My feeling is this is a plan to get your Web address, your telephone etc etc and then you are bombarded with emails of what they sell.
If it's free then give it out and if I then feel their product is worth it I will consider purchasing, just don't ask me for my information.
