Read level comparisons as indicative, not precise. A market's basket cost reflects which items and stores cleared our sample thresholds there, not only genuine local price differences, and that composition varies between markets. The month-over-month change is the like-for-like figure — it compares the same items at the same stores, so composition cancels out.
