I'm not sure about betterbidding's blocking policy but they are extremely adamant about using their links. I recommended to use a cashback program such as Mrrebates or Bigcrumbs to get a few percent cashback on Priceline purchases and that post was deleted within minutes. Every post I've seen from the moderator says you should click through their links in large letters and they are not open to any discussion involving other options. I am however pleased with their bidding calendar function.

Of course biddingfortravel and that horrendous Sheryl witch is a hundred times worse (I don't normally badmouth ppl in public forums but she is notorious).
