I try to do my own as getting things delivered here is like saying...hi I live on mars, can you send me a thing...typically it just means my P&P charges are double the price of whatever i am trying to buy and often it just makes things non economical. rather than be deterred by costs, i just go see what I can make similar or the same.
The other thing I make lots of is my own skin care products. from soap to moisturizers and or creams and salves to help injury, cuts, abrasions, strains and worse.
I like flowers for this, things like Calendula which are easy as shit to grow, easy to dry, easy to put in oil and so easy to use. I try where i can to avoid any shop cosmetics. I am lucky here tho. I have access to books in Russian and so on, old old, that helped me rediscover medical plants growing all around me.
I make my own Redbull type of drink, using malic acid naturally fermented from common weeds growing here everywhere. I try to live without needing to consume from sources that dont care about me or the planet, but its fucking tough and requires lots of efforts on days when effort seem the hardest :) I have made lots of mistakes and lots of mess in my life :) Sometimes tho, things work just the way the book said and its good to go
