Buy anything from KFC. 5p dip, get a receipt fill a online survey, takes 1 min get a code and you get 20% off your next purchase. Which entitles you to another 1 min online survey again for 20% off your next order. Have been using it for 2 weeks, never ending 20% off!!! You need a receipt as it asks for details off it.
I'm retarted ;)
