With so many ways of getting content, what is your primary way of reading manga? I know one of my friends gets hers from print, but she also has some digital medias as well. What do you like the most?
At local used bookstores - there are MANY to choose from.
The library is another great resource as well. I know in my library I can pretty much request ANY book and they are able to get it within a week or so by just requesting it on the online system. I believe they have a budget every month for this particular service. PLUS it's all free.
