I'm in NS and I discovered a couple places in ON and westward that makes peanut butter. My plan, to purchase a case of 10 or 12 jars. Which I can no doubt consume myself in a year but will consider trading with neighbours for eggs or produce during summer time.
For a few years we collected points, simply a goal to see if we could reach 1 mil and then cash in for groceries at the local Real Atlantic Superstore. Reached the goal and then some, got to about 1.5 mill and then started using all the points for all grocery purchases in store. Once the points were depleted, the account would no longer tally points on purchases where points were offered. Tried the same methods of watching the sales, etc, and would buy the things on sale as needed. No points collected on purchase. Gave up trying, and now shop wherever is convenient. I was at the local store last week for a few things and the cashier said that now a person has to open the app and accept the offers, then buy the product during that sale period in order to collect the points. Yeah, no, not gonna do that anymore.
Besides, holding on to points while grocery prices continue upward only devalues the points at a future redemption date. Might as well cash them in as you go.
