Good point. It is mostly the utilization margin: households switching off the freezer during the rationing and not switching on afterwards. Technically, I find no significant effect on the quantity of freezers owned by households, but I find a significant reduction in the quantity of freezers permanently switched on. Unfortunately, I did not investigate expenditure on food yet, I am still trying to look at this. I agree that freezer can help people stock food, but the overall saving is less clear since it depend both on the food discounts and the cost of maintaining the freezer switched on. On that, anecdotal evidence from the supermarket association suggest that the sales of frozen food dropped and the sales of raw food increased during the rationing.
