This was my big preparedness item as well, I bought another 3 months of TP, as well as making sure I had plenty of dish and laundry detergent on-hand. And chili sauce. You know- the pure essentials.
I generally don't have disinfectant on hand, and I was low on isopropyl alcohol. Now my first aid supply is topped up.
I could still use some stuff (hey--is that all the garlic I have?), so will probably make a couple more trips before I'm ready to lock myself away.
