I used to buy tons on manga- I have the full runs of long manga like Rurouni Kenshin and Eyeshield, plenty of shorter series like Deathnote and .hack: Legend of Twilight, and tons of other assorted stuff. I don't buy as much stuff now because the stuff I like reading doesn't get released (smut, things like Molester Man,
), and I am past the point of wanting to start any long series.
The way I read manga now is thru my subscription to SJ Alpha (where I read Nisekoi, One-Punch man, World Trigger, and Blue Exorcist), and when I see someone post something in this thread that I find interesting, and then I read it on my iPad or computer. I'd embrace digital manga more, but the pricing is messed up. I buy tons of stuff in Comixology, where issues are 1.99 and a trade of 4 issues is someing like 6-7 dollars. They also do tons of sales, like the Star Trek one they did last week (all Trek comics were 99 cents, and most trades 4 dollars), their weekly Marvel sale, ect.
Viz never does any sales, and prices all the books at 4.99. So if you wanted to get caught up in Naruto, you would need to spend something like 300 dollars for 60 volumes. Which means that there is zero chance I ever buy a single chapter from Viz, even if I wanted to start the series.
They need to find a way to make stuff cheaper, or at least get it on sale sometimes.
