Re: Shoe drops
possible exception is coffee. There's "plenty" of coffee in the world, but could be that if everybody in Europe and the US throws 5 bags on the cart on their run through the store it puts the strain on the system, even if Starbucks and the Italian cappuccino cafes are shut. Don't know, trade either side of that at your own risk.
Of course coffee isn't particularly perishable- unlike produce-or meat which either gets eaten, frozen, spoiled or bigger.
