These folks are total jerks, constantly spamming you with nonsense. Do yourself a favor, and assign their emails to SPAM. Even then you will still get your email bombed with their garbage.
Every single day there is, "one last step to win." Yeah, like forever, and they want you to scroll through 4 pages of crappy products before you can submit an entry. Even then you will get, "an order would be appreciated." Well, I'll place an order when that multi-million dollar winnings is mine, but in the meantime, I don't think so.
