You should always have a decent med kit lying around. Surgical supplies. Medicine. All over the counter stuff. Nyquil. Toiletries like extra shampoo and soap. Antifungal pills.
Also substitutes like chamomile and even better chamomile seeds. A lot of herbs have medicinal properties and they are way to dry and store.
Have a garden. Have a hydroponic garden. You can buy a fish pump and hdx tub from home depot and use the lid as your tray. For like $25 you can make a hydroponic set up. Weed is tradeable but also great for heirloom tomatoes and other herbs and small fruits.
Crossbow and target for practice. Silent killer.
