An honest question deserves...

<p>I was just thinking, why do I have to choose between Pick n Pay & Woolworths, Dischem & Clicks, Total Sports & Sportsmans Wharehouse? Why does Discovery not just give 25% cash back on all of them if one qualifies? Then I will be a ble to buy my Vitality item at the cheapest store. I benefit buy paying less of the item and Discovery benifits by paying a lower cash back or am I missing something here.</p>
