Not sure if this is on here already but couldn't find it, but I have a free app on my phone called Virgin red. Basically every day there is a little fun mini poll which takes 10 seconds if that, and each day you complete it you get points, the points add up and unlock vaults. The vaults can be anything from huge reductions on Virgin products to competitions for one off prizes. I've had the app for approx 3 months and won a bottle of prosecco. In addition last month if you managed to open the top vault you were guaranteed a bottle of wine (I'm waiting delivery of this). Thought this may be of interest.
