Seeing as all the purchases are from Superstore, I would guess that either you didn't load any offers for those shopping trips or you didn't purchase any products that qualify for any offers. Only Shoppers Drug Mart will give you base points for every $1 spent and Esso for every Litre of gas. When the program first started a lot of people had some confusion about this.
If shopping at Loblaws, Superstore, No Frills etc then you don't earn points just for spending unless you have the PC Mastercard or a specific offer on products ie: 200 pts per $1 on beef, spend 150$ at No frills get 15,000 pts or other in store offers that everyone gets like 3000 pts for every $8 on kelloggs cereal. Load your offers each Thursday to maximize your points.
