I don't know who needs to hear this in the Year of Our Lord 2022, but...
GO TO THE LIBRARY.
Seriously, get a library card and start browsing and borrowing online and off. I can't speak for every library across these here United States, but in nearly all of the places I've lived in (including the 'burbs), the library has been clutch. The library saves you money, time, and supports your favorite mangaka. It's a win-win-win for everybody. If you, really enjoy the book, then you can purchase it later at your leisure.
What's that? Your library doesn't have a decent selection? Request manga. Find the forms on your library's site or ask the librarian. (They won't bite, promise.)
That's it. That's the tip.
