The premade soylents are pretty good, and I regularly have them with a protein bar as my lunch. They’re pretty expensive in my opinion, so I try and look for them on sale, but the ease of not having to prep lunch is often worth it. I try and keep it under $2 a bottle for the 14oz ones, which still feels expensive to me, but some of the lunches I prep are around that cost, and it’s way cheaper than going out to eat (I keep a spare one at work in case I ever forget to bring lunch)
I save the butcher paper that comes in a lot of the packages I order, and use that + twine to wrap things. It can look cute and old school and saves a bunch on buying wrapping paper (I also try and buy that on massive clearance after Christmas, and if I can get more generic or even just winter themed paper I’ll angle for that to use for birthday gifts later in the year)
