TopCashBack in the UK, the web based rebate site, is offering a higher level of rebate on Hilton hotel bookings made at the Summer Sale rate. (non-refundable/changeable). Sale ends 23 August and you must stay by 27 September. Not clear how long the enhanced rebate will last.
Their normal rates are – 8% for hotels in Europe, Middle East, Africa & Asia Pacific Hilton bookings and 6% elsewhere.
If you’re not a member of TopCashBack you can join here. (I receive a small commission if you join and then earn cash back).
It usually takes several weeks after checkout from the hotel to get the cash back, and of course, you can convert the cash in to either Avios points or Tesco Clubcard points which can then become Avios points at a better rate than the rate if you switch the cash straight in to Avios.
