I just caught a Tesco advert on the idiot box tonight. In the advert they proudly boast that if you find that their product is more costly in their store rather than at Sainsburys, Asda, or Morrisons, they’ll give you a coupon for redemption once you pass through the checkout.
Sounds good on the surface doesn’t it?
The customer of course is going to think to themselves that Tesco is being wonderfully philanthropic and will return the following week to redeem their voucher.
All Tesco has to do is add a couple of pence on dietary staples such as bread, milk, cornflakes, whiskey, water, tea, coffee, whiskey, and butter, etc, each week. Lo and behold, their customer base is secure at no extra cost to them.
