What kind of pie filling?
A friend told me an anecdote once of an acquaintance who was a car salesman. December is a slow month for them, and they sold half as many cars as usual and made twice as much money.
Remember, they make it up in volume. No, wait...
Anyway, you just never know what's going on. They'll never sell at a loss, but if the store is about to close and they are going to liquidate the inventory, then yes, they'll take any reasonable offer. Or if they have quotas on volume instead of net.
Anyway, to answer the original question: No. It's likely that discounts are set at the corporate level, and they'll have the financial resources to hold out for a few months until the economy and the market recovers.
Also, I suspect that many people will be trapped in their homes during these voluntary or involuntary quarantines, and what do we do when we're stuck at home and get tired of having sex and watching Netflix? We shop on the Internet. So sales will be up, or at least even.
