I shop the weekly specials mainly for meat and vacuum seal them and freeze. I’m currently eating meat at last years on sale prices. I’ve given up my smart phone for a $20 a month flip phone.
But I’ve lucked out recently with bartering. I live in a rural area with most people having 2-10 acres of land. Some city dwellers have moved into the area and want to live the country life and become self sufficient. One family asked around and found out that I used to have laying hens and approached me for some advice. I showed them how to build a coop, how to maintain it and the breed of chicken to buy. I now have an unlimited supply of eggs. One thing led to another and now they want a garden. It’s too late for a spring garden here but I have them busy preparing for a fall garden.Next year will be the spring garden. I now have a source of fresh vegetables. I can no longer do these things myself as age has taken a toll.
I actually enjoy sharing what life has taught me with others that are willing to learn.
I like your ideas best, so far. :)
