Booking.com is killing it right now.
1st, sign up for $25 back (or 10% cash back) after first stay. You want to sign up for the account using the $25 link first, as it will not stack otherwise with the offers below.
2nd, you are then allowed to earn 3 separate incentives per year. Conveniently they are currently offering 3 separate cash back incentives that are worthwhile.
Our view: In the past they’ve had some great cash back per booking offers and we regularly feature deals here that are bookable at the site. While they don’t offer traditional coupons, they do offer a “Booking Genius” rewards program to their most frequent customers. To qualify you simply need 5 bookings in a year, and then you receive 10% off properties that have opted into the program. Less talked about, is that there is no minimum spend requirement for the five bookings. Currently, they are hosting “Genius Week” where you can opt-in to get the benefits of Genius without the 5 stays. So 10% off this week! If you are in or visiting an area with cheap hostels, it’s worth it to get the five stays as they will stack with these ongoing offers. You can do this for as cheap as $10 total for five stays at a prepaid non-refundable hotel.
