Okay, so since I do a bit of data analysis for a living, I was curious as to how things broke out on my recent canning adventure price-wise.

It turns out, it’s cheaper to can your own jams. This is probably because I like Bonne Maman preserves, so I was comparing it to that, and not the cheapest available option in the grocery store.
I had assumed it might be more expensive. I ended up quite a bit cheaper, due to the recent inflation.
Start up costs were not taken into account. I bought a cheap canning kit off Amazon: https://www.amazon.com/gp/product/B0BC5FKBHX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
As well as three Ball brand canning cookbooks. They were free due to that e-credit Amazon gives you for being patient on your deliveries.
I also bought two cases of canning jars, three if you count the Verones ones that I disliked.
I’d estimate in start up costs I paid around $100 all said and done, but I ket to keep all that to continue using going forward, so I am considering that an investment and a sunk cost. I just didn’t feel like depreciating that over the life of the canning equipment.
I think, this outcome would not have been the same pre-pandemic and pre-corporate greed fiasco. Every product on the market is showing what happens when corporate greed goes unfettered. This makes making my own jam several dollars cheaper for 8 oz container. If companies weren’t shitty capitalist nightmares, I would have broken even at best.
