I recently got a loyalty card for my local supermarket. As a reward, they sent me some vouchers off either shopping or petrol (on alternate weeks) if I spent £20 per week over 4 consecutive weeks. If I spent all 4 vouchers, there would even be some bonus points.
Having used some of these vouchers, they then sent me some more vouchers if I spent £30 per week over the next 6 weeks. This felt like a very sneaky way to get me to spend more money. Were they trying to get more money out of me? Would spending more money actually result in bigger savings? I decided to try and find out…
