"How does the motorpoint thing work then?"
If you get say ?10 worth of clubcard vouchers sent to you a quarter then if you change them to deals vouchers you get 4x value thats ?40 in motorpoint vouchers (motorpoint is a national car supermarket).
Now, it's possible to buy things that are on promo and get much more ? in car vouchers than you paid for items you bought.
Rather than go into it in depth in here all I will say is over a year of collecting I spent about ?1500 on stuff in Tesco (mostly toiletrys ie shower gel, shampoo, deodrant, some baby products, confetti, garlic tablets) and got ?4000 towards my car.
I got a ?5000 car. (So I paid ?1000 and used the ?4000 vouchers) so got car half price.
But even better than that our family will not need to buy shampoo, deodrant, shower gel etc for the next couple of years, I have a mega stockpile, so I will be saving probably about a ?1000 in time... So car cost me ?1.5k in effect less than 33% of screen price..
If you want to know more google the phrase "paid to shop" and you will find a forum full of folk who are making the most of Tesco's vouchers.
Car is a 55 plate mazda6 2L TS with 40k on. Macrae and Dick want ?6500 for same car.
