Spar "Zyliss knife" campaign - the worst campaign ever

Spar is running the worst campaign ever, as you are not able to fulfill what you are campaigning. Please don't tell your clients it is your supplier, if you plan a campaign like this you should be able to check your turnover upfront to see how many full collector cards you might get, so at least have enough knifes available for a minimum of half the collector cards printed and handed out to your customers. Only start a campaign when stock is already available in order to avoid frustrated customers who will go to competitors that do their homework better before they are campaigning... Actually all stores in Milnerton area are out of stock since beginning of November already, meaning not even after a third of the campaig duration! How can Spar run a promotion like this without making sure that there is enough stock. We got 18 (!) full collector cards, meaning 3x full sets of knifes. We await you to contact us within the next working day and let us know how to get those 3x full knife sets in order to avoid a complaint with the advertising commission and the NCC.
