Is it fair to use the last 2 years as a baseline (perhaps for temporary price hikes, but we are seeing how "temporary" those are...)?
Grocery is different, because it's set up for dynamic pricing based on fluctuating market conditions. They also operate on razor-thin margins. For prepared foods, you definitely have to look at the last 2 years. Most of those business are small, cannot operate on dynamic pricing, and can't afford to be wiped out by fluctuations in material costs.
