Hmmm... So you've got food prep, computer stuff, hygiene....

The only amazon thing I can think of is various tools, a good knife, or a couple good books. Maybe a set of wrenches for your car, or a portable battery charger so you can jump yourself without another car.

I've always been grateful to own a nice pair of ear buds with adjustable rubber ear pieces. That is if you listen to music a bunch.

Or one of these little maglights

I tried to link things that are genuinely quality products for a good price.
