Make the first purchase easy to recover
For a first e-book manga purchase, check where the title will live after checkout. Library behavior, device support, and account access matter more than a small discount.
You should be able to reopen the manga without guessing which store, app, or account you used.
Test the reading screen before buying
Use the official sample to check page turning, zoom, text size, and color tone on your main device. A title can be good while the reading setup still feels wrong for you.
If the sample feels smooth, then compare price and volume count. That order keeps the first purchase simple.
Start with one title, not a stack
The first goal is learning the store flow. Buy one title or one volume, confirm the library screen, and then decide whether to build a bigger list.
