This is not a drill: the Girl Scouts have set up a website—www.girlscouts.org/cookiecare—where you can order cookies and have them shipped right to your front door (make sure to use that actual website and not buy them elsewhere online). After typing your ZIP code, the site provides a list of Girl Scout councils in your area that are still in their "cookie season," and it also helpfully provides the date when they'll be mailing out orders, just in case you want to save the Tagalongs for a little later in your quarantine.
And if you're feeling extra-generous, you can even buy boxes of cookies to donate, and the Girl Scout council that you've selected will distribute them to hospitals, medical centers, or first responders in their own local areas.
