In the past year, the cash back rate for InterContinental Hotels Group (Holiday Inn, Crowne Plaza, InterContinental, Holiday Inn Express, Candlewood Suites, Staybridge Suite etc) bookings has varied from 6% to 21%. The usual cash back rate has been around 7%.
All these sites pay using PayPal except ShopAtHome that mails out a check to an US address. If your payment is greater than 25 GBP, Quidco requires you to have a UK based bank account.
If you have made non-prepaid reservations and can still book at the same rate, you can just cancel the reservation(s) and book at the higher cash back rate. I usually try to do my immediate bookings when they have cash back sale going on.
