While perusing the aisles, Shaffer noticed an in-store deal in which shoppers could instantly get $3 back for every seven items purchased. It wasn’t a huge discount, but she used it to pick up healthy foods, like a pint of mushrooms. But saving money is not without its costs. Shaffer said she used to buy whatever she wanted, but now she has to stick to store brands and what’s on sale. “I’m not going to lie and say you don’t make sacrifices,” she said. “I used to buy filet mignon. Now I buy ground beef.”
