Turtle Wax products give free cinema ticket for Transformers film!

Went to Halfords today to buy some alloy wheel cleaner and I saw a special offer from Turtle Wax. For £10 I got Turtle Wax car shampoo for up to 30 washes, Turtle Wax liquid car wax and Turtle wax Alloy Wheel Clean! On top of that I also got a free ticket to see Transformers - Dark of the moon. These three products come in a cardboard flat box and it says on the front I saved £4.47 buying it like this. There also are other cleaning products like this one for sale by other companies going for £15 with 4 items and £20 for 5 items both of these also come with 2 cinema tickets for the same film. Now normaly i'd say there must be a catch somewhere but there isn't! I think this offer is a very good offer indeed especially now that most cinema tickets cost almost £9 each!
