Think about ordering non perishables online where you can.
We’ve been using walmart.com, kroger.com, vitacost.com, etc.
Spray down the box with some antimicrobial when you get it, let it sit for some minutes then stash in your garage or shed for 10 days or a cpl weeks to let it mellow...
Oh good grief...I’m not going to be spraying down box’s or go that far. I’m set here if it comes to that extreme.
