Consumer prices for groceries rose 12 percent year-over-year as of November, according to Labor Department data, and for those that like to bake, the news was worse — flour cost nearly 25 percent more and egg prices shot up almost 50 percent. And yet some product categories were less affected — meat only rose about 1 percent — and some actually became more affordable. TVs were on average 17 percent cheaper in November vs. the previous year period.
