For many homebound persons online shopping is the only way to get their goods now more than ever.
If you are in a risk group, it could be a very convenient way of shopping.
I personally ordered some face masks for my family. Even if the government has not issued any clear guidelines yet, face masks will prevent others from getting exposed to your germs. They will not prevent you from catching a disease. However, if everybody is wearing them, more people will be protected.
Whilst being at the surgery, on a bus or in the tube or caring for an elderly, these face masks can give you some reassurance.
In these times online shopping is a way forward.
