If you have Covid you should be quarantining. You could pass it to the person driving you, and then they could pass it to anyone they come in contact with. Getting corals isn’t a priority, it can wait until you’re no longer contagious (if you got it on Friday, you are likely still contagious,
you’re supposed to isolate for 10 days). If you absolutely can’t wait (which, why?), just have the person pick up what you need and have them drop it off on your porch. There’s just no reason to potentially infect someone else to get some corals.
