hotelscombined is a company I used to work with that provided a hotel price comparison site similar to the way Skyscanner does for flights. They often had good prices for TTR. I received an email recently that they will no longer credit affiliates with any sales and will not be paying the usual commission. Most of you will know that bookit recently went into administration, I think other travel companies will follow. If they are refusing to pay the people that send them their sales I would guess they are having financial difficulties. I'd recommend not booking with them for now.
