If I am not mistaken, you have to register the card before you can get any points.
I purchased some PC yogurt the other day, it said it was worth 200 points. When i got to the till and asked for the PC plus card he scanned it and gave it to me, but when i went online today to register it showed I have 0 points.
so im thinking the scanning part for a new card just activates the card, but you still have to go online and register to get the points part started.
or am I mistaken?
