Looks like Quidco has started doing Cashback for Hilton reservations again. Cashback is 6% for America bookings and 8% for rest of world. Hope it works better than previously when I had quite a few declined and payments refused and Quidco could never give any reasons. These rates look better than Topcashback, which currently pays 2% and 4% respectively and Cashback has to be taken as Tesco Clubcard points.
