I started this silly escapade to data check my perception that Chex cereals never go on sale. That has proven essentially true at my home supermarket. In the process, though, I've also seen some other patterns. I've also verified that Chex are cheaper at Target. Hold onto your hats. Deep dive time.
The quarterly summary actually shows that ice cream is more expensive in cold weather months in Pennsylvania. It's cheapest in the early spring. Buy your Chex in Q1. They'll keep essentially all year. Buy your butter in the fall/early winter. Chest freezer? Probably worth it.
The cheapest ice cream crown is well-distributed. Although the store brand has the lowest base price, the name brands are more often the cheapest by a long shot. Some brand is always on sale. Don't be a sucker by paying full price. Mmmm, Breyer's.
