There have been many prophecies and visions of black outs or grid down scenarios. It is very important to have the information you are saving PRINTED, so you have access, no matter what. Also owning BOOKS on gardening, canning, cleaning wild game, and minor medical treatment (I purchased a military medical field guide). Also a small surgical kit is a good idea.

Print out repair manuals for all your small equipment (like 4 wheelers, chain saws, etc. )

You can purchase FISH antibiotics and antifungal medications (these are real antibiotics with no additional ingredients), but you do need to research what each medication is best suited for.

An "old fashioned" Rand McNally Road atlas, in case you need to travel with no internet access.

Save all your old half burnt-out candles. They can be melted, and new candles made as needed. Purchase a package of candle wicking for your new candles. Suspend the wick in the center by wrapping around a pencil, and pour hot wax into container.
