Hoping for insight from shoppers

I'm trying to figure out if I should report this woman who told me she was using her husband's phone to shop my order. A couple of weeks ago was the first time. I went to the door, expecting one of my preferred shoppers and was surprised to see her on our doorstep instead. I just said "hey, you're not Sean!" (But in a kinda jokey way) that's when she told me. We just received another order and it was her again. Anyway, I know everyone is struggling so l really am just hoping for insight on whether or not I should be doing anything about this. How bad is it to shop under somebody else’s name and account? Thanks!
