Compare the store experience, not only the price
For e-book store comparisons, price is only one part of the choice. Library layout, app comfort, sample availability, sale rules, and account recovery all affect whether the store fits you.
A cheaper title is less useful if you dislike reading there or cannot quickly find the series later.
Check one manga across stores
Pick one title and compare the same volume across DMM Books and another store. Look at sample length, final price, device support, and whether the series page is easy to follow.
This avoids vague store comparisons and shows how each shop handles a real purchase path.
Keep commercial links transparent
When a guide points to an official store, treat it as a pricing and terms check. Confirm the latest conditions on the store page before deciding.
