I agree with the other posters who pointed out that strategic shopping is a way of life. Big meat sale here in our little town, and I stocked up plenty of boneless chicken breasts and extra lean ground beef, apples and bananas. I am a smarter consumer now than I ever was.
But caution is warranted in that you need to read labels and make choices. Some splurging is fine; eating
only overly processed, highly salted/trans fat food is a bad choice.
But I do love the occasional frozen pizza (when I get them at a good price that is!)
