I have the
Google Rewards App on my phone.
It has saved me a lot of money on eBooks!
Or it can be used for Apps or Movies.
All you have to do is download it and it will send you Surveys to answer.. Eg have you visited a shop, what day was it etc.
I have been using it for a year now and have had the grand total of £90.74 up to today!
Go for it.
