Do you buy digital or physical?
Personally I started all physical but once I ran out of space for the books and figures I went digital. I actually almost never read ero manga physically because it's hard to flip the pages when you're jerking off. And you want to keep the book new and just sit back and easily click with your mouse. Collecting is cool and all but eventually you'll realize you don't have unlimited space and time and money. Digital is the future anyway. More convenient, easier to jerk off and virtually unlimited space. And no wasted money on shipping.
For both books and games, there's only one rule - no physical, no sale.
I started by buying physical stuff from here whenever there was a special sale that allowed me to afford the expensive costs of shipping overseas. But since those deals died out pretty quickly I now only ever buy digital, at the very least until I can buy directly from Fakku without selling my kidney for it.
It depends on the product.
Physical, out for the whole world to see. I wonder why no-one comes over anymore?
Mostly I buy e-books, paper books I buy rarely because they're more expensive.
If I have a chance or if I find it, I buy physical
If it’s something I really enjoy I’ll buy it physical
