Really slow cashback, but great way to travel
The details do say that you'll receive cashback after booking is completed, and 8-12 weeks is quoted. I've so far been waiting 8 months, so long that I'm almost ready to book again, but unlikely to go through Quidco this time.
Suntransfers is a great way to travel, and you'll never use a coach transfer again (although they are a middle man company, the drivers are private). Met by a uniformed driver holding a name board in arrivals, who carried my luggage the short walk into an immaculate, almost new Mercedes limo van thing. A brisk drive to the hotel, to the door and he unloaded luggage into hotel for us. Cheaper than a regular taxi, with added luxury. An excellent service, always travelling this way in the future.
