Old e-mook magazines with the gift?

Hi
Trying to find the old gifts that come with the E-mook magazines. Ever hear someone say second hand book stores? But i do not know how to find them.

Please share with me if you know. Thanks so much!

If it needs to be brick-and-mortar stores, you can try going to a Book-Off branch, or walk around towns like Jinbocho, famous for its many second hand book shops.

If you simply need an E-mook, Google is a great way to find them. There are so many here.

If the publisher (Takarajima sha 宝島社) still has them as back numbers, you can order directly.

Most of the case, people buy those magazines with 2 reasons.
1. Mainly to get the gifts, so even you find at the second hand shop such as book-off, usually they sell magazines only, not with the gift.
2. If the gifts are really popular ones, people want to sell them with higher price via net auction (Yahoo/Rakuten) or personal used item section at Amason/Mercari, etc.

I see . I wonder where the people get the gifts from old magazines from? Because they say they can only buy the gifts and no magazines ( they claim from some specialized shops like secondhand book store..) Thanks!
