When I buy, I buy only 2 weeks of food, medicine and toiletries at home. And replenish it once it empties out.
InshaAllah tomorrow I shall increase the dry stock to 3 months.
And by the way, there's no reason to panic. It's like flu and more people die in road accident, heart attack, cancer or diabetics in BD than these viruses.
Which is why I am stocking a little bit, as everything is normal, nothing to worry about and no sin in stocking in normal times :-)
