I would have thought food prices were less seasonally dependent than they are now, on the grounds that out-of-season food simply didn't exist (outside of preserves that were made during a seasonal glut). An avocado in a British supermarket costs about 90p right now. In season, you can normally get at least three of them for that money. Similar price changes occur for soft fruit etc. 100 years ago (even 50 years ago), your diet, rather than your food budget, would have been the thing that changed with the seasons to match availability.
