Weird, you sure you've never registered your email with them or an affiliate company?
Are you going to take them up on their offer though ?
Interesting. We must be on different lists too. I have not gotten that one (with the same picture) but I have gotten 2 or 3 others that are more or less the same deal or similiar deals in the last few months.
If you updated your detector then you have to register your email.
I got a similar email from Bel
