Did build our house on my own. It is not finished yet, but I can't wait once it will be done. Saving me a lot of $$$ too. Not all works tho, like roof, but I would, next time, as the prices are rocketing to da moon. Hard work, sure, double hard when I am somewhere and forget some tool, need to walk twice. of when there is no one who would help hold some heavy object.. But funny, with some tricks I did lift 355 pound linter without much effort.. A lot of fun and memories during this hobby of mine.
Other than that, a lot of crazy things, like buying ¬96 cans of tuna for good price, but mainly it was for preps :D After 4 or 5 years, I am still eating these. Taste the same..
Or - i travel abroad with six 20L fuel canisters in the trunk. (6x5.28gal) as I save 10c on each liter. (170liter was the max i took) its like 10% saving on fuel. Since I travel 14miles and 14 miles back, I need to take not only 1 full tank, but rather 3, to have real savings on those extra two (6 canisters). looks funny, I could post some pics for some laugh... Also, people laugh and ask about MPG, since its hothatch of some kind..
