Who knows what the future holds, btc is gaining popularity and recognition everyday that passes, new stores are accepting btc slowly, if using btc to buy groceries is more cheaper than using fiat I think people will start using btc to buy eventually in the near future, for now, many people are still very comfortable using fiat to make payments whether it is online or offline.
Basically it's part of what we can do to take advantage of our current situation, transacting using bitcoin might be hard in the beginning because you might need to copy paste the entire wallet address, and the other option which is to scan QR code is also hard considering its security flaws. If ever bitcoin transaction develops, we can use it to buy literally anything else faster than fiats. It just needs to have a few considerations.
On the other hand, buying goods while you are at home is more appropriate, you don't need to go outside as they will directly deliver it to your home and what you just need to do is to sanitize what you bought.
