There is still time, a window of opportunity, to keep prepping.
The best way is to shop often and buy just a little extra every time you shop. Not enough to be noticed, but enough to make a difference.
Don’t forget salt. It’s critical for survival and is not something readily available in nature except in a few locations. If supply chains disruptions happen, stuff like baking supplies and salt will not be had.
Also, don’t forget first aid stuff and OTC meds.
Don’t forget seeds and garden tools.
