Not as good as the 12% before but may still be of use to some.
And yes, some prices do get inflated. So it’s best to compare cashback vs non-cashback price.
Cashback is ineligible on the following:
Car rentals, flights, and non-accommodation bookings
Use of any Booking.com refer-a-friend links, codes or any non-Cashrewards incentives (offers, links, newsletters, secret prices), unless stated as eligible on this site.
Travel that is not consumed
Items that are cancelled, returned, exchanged or refunded.
GST, other taxes and delivery fees.
Fraudulent transactions.
Purchases using any type of discount which lowers price advertised on the Merchant site, including but not limited to employee discounts, student discounts and price-matching.
I recently booked a holiday. The cashback through CR was 10%, but the price of accommodation going through CR was ~10% higher, so I noped out of it.
