Supermarket guru Phil Lempert says the way to legitimately beat skyrocketing prices at grocery stores is to shop smartly and to be aware of shrinkflation. To avoid raising prices, Lempert says some companies have changed the size of their packaging. It's apparently all in an effort to avoid raising prices but he says that often means they're actually giving you less than before. According to Lempert, a good way to avoid falling victim to shrinkflation is to buy in bulk.
