Generally I really like Waitrose - good fresh produce, friendly staff. However, it irritates me beyond measure that when they occasionally send me ‘money off’ vouchers they are invariable £7 off a £70 spend, with 8 vouchers provided for a 4 week period. I live alone, I probably average £30 per week at Waitrose, these vouchers are of no use to me whatsoever - to benefit from them all iD have to increase my spend to £140 per week. Tesco, on the other hand, sends me vouchers that work on 10%or 15% off a £30 spend, makes so much more sense. So for the period that the Tesco vouchers are valid, I’ll shop there more frequently. How difficult can it be to check my average spend and then send appropriately valued vouchers? Or is this just a tick-box exercise?
