Reporting here-- an update from an older lady just trying to stay alive and also to flatten the curve.
Someone on here said maybe today would be a good day to beat the crowds. It was Day 12 for me in isolation, but I decided to go shop at Kroger's Food4Less in San Diego. I couldn't go early for the senior special time. I went around Noon. Let me tell you, Kroger's has it together! (in the South, I think they own the Publix chain?) I was impressed!

They gave me a disinfected cart, and no wait to get inside. They had decent, sufficient stock on hand. Wow, I got everything on my list except flour. No flour at all on shelves.
Listen, I got a big package of 12 rolls 1,000 sheets each of toilet paper for $6.50! They seemed to have plenty of meats and vegetables. I needed some of the suggested OTC headache and cough meds, just in case I got the virus...yes, found the OTC meds I needed. No price gouging, prices were almost the regular price. NO long line to pay either. A lot of shoppers, me too, had on masks. I had disinfecting wipes handy. Ready now to go back into a longer self-isolation, but now I have enough supplies to go 20-30 days or longer if needed. I promise stay home, if you'll just help me stay sane.
