You need to start stocking food. You can do a lot if you start early. Unfortunately, “early” might have been yesterday. Now we’re way past early, and you need a reasonable plan to get food supplies that will store well and don’t cost too much. Buy extra, use FIFO. Go ahead and buy more food than normal when you’re out shopping, and set it aside as preparedness. Use the “first in, first out” rule to eat your older supplies first. Keep rotating your supplies so you never abandon food “way in the back.”
