Too many things to list (and we covered that in some of the other threads). But, as general guidance, I've been asking myself "What do I need on hand to stay out of the stores for the next 6+ months?" I've also asked "If I couldn't get ____ from the store right now, what could I use in it's place?" Extra food, cleaning supplies, masks, gloves, items for the kids/baby, feed and supplies for the animals, etc.
Overall, considering my budget and situation, I think my preps were in decent shape even before this virus mess (at lease for this current scenerio). However, I've spent a lot of money and time lately topping things off as best as I can, really thinking things through so that I make the best use of my money. There are dream preps I wish I would have on hand now, of course (better/more masks, medicines, rabbits, more solar lighting, etc.). I'll never, ever have enough. But I'm still in a better situation than most.
