If you don't care about the timing or leave near the suburbs you can drive around on Jan. 1st or maybe even the 30th and lots of people throw them out like I said...free trees and you can have like 5 lol.
One fits in a midsized car pretty well or you can twine it on top of a small car. Just an idea. Trees aren't cheap.
Or if you have some land you can plant one. Much cooler that way because the first year it'll be Charlie Brown (ish) and so on.
My dad had a fir tree that was a small as me at 5 or 6 and then eventually was 20 feet tall. Pretty cool because the trees are nice even without lights and you can bury a light cable so that when it snows you can plug it in
I can't stand fake trees. Just not the same. It's something if people want to decorate it...my mother uses a fake tree because it's free (got from her mother) and there's no cleanup but they don't smell. Something though.
I had a dinky one in my apartment like 2 feet tall I got at Walmart or the dollar "tree" and it was "something" but I wouldn't put it up again.
Not sure if you know what the bonsai process is but you can miniaturize many different types of trees and since the roots need heat you'd have to bring a fir bonsai indoors in winter anyway.
