Making your shopper card count [View all]
I went grocery shopping last night, got $80 list price of food for just under $70 by using my store shoppers card to the max on every item I could. I calculate that as a 12.5% savings out the door.
The store is a bit sneaky and changes this stuff around every week so you really have to pay attention to the labels to get the most discount on what you need. It helps if you're reasonably comfortable juggling a few numbers to figure out what the best deal is and you have to be willing to forgo specific brands. The store brand of just about everything I've tried at the Ingles I was shopping last night is fine, can't really tell it from the advertised brands and it's usually (but definitely not always, pay attention) cheaper than the national brands.
I probably added fifteen minutes to my shopping last night by being careful and saved ten bucks, I figure that's not far off forty dollars an hour return and it made the difference between a bland diet for the next ten days or a more interesting one.
