Booking.com: 9% Cashback (Was 4%) @ ShopBack
I may be wrong but this may be the highest cashback ever offered for Booking.com.
I might have to cancel some bookings and re-book.
Excludes taxes, fees or additional extras
Cashback is only payable on Accommodation
From 19th Oct 2018 onwards, Cashback is also valid on purchases made on Booking.com app by clicking through the Shopback App
