This!! Lots of plans online you can lookup. Not super expensive. Check your zone and know when to start your seeds.

Every little bit you don't rely on the big business matters. I end up growing so many tomatoes in my two little raised beds I give away a bunch to neighbors and friends.

Agreed. The only large chain I trust anymore is Costco. Lots of online ordering for dried goods as well from online distributors outside of Amazon. Thrive market and smaller businesses like Rancho Gordo too.

Even a little bit helps here and there. Maybe see it as a more do what you can? Online ordering shop small businesses like Etsy for gifts, farmers markets and pop up stalls in the summer when produce is available. I'm even starting a small backyard garden. It's not perfect but it's something.
