Ive always used momentum, and i cant tell the difference between that and V-power.
Tesco's clubcard points are good but, they have recently halfed the value of the points when you fill up. No longer a £1 per point, its £2 for a single point. ( or 25 points for £50)
Unless you use a Tesco credit card, which ive aquired recently, that then still gives you £1 and 1 point, getting more value for money with your clubcard points.
That and all purchases using Tesco's credit card, you earn 1 point for every £4 spent.
Every little helps
