Found a Mirai Carry alternative at the convenience store for 1940 yen which is about 19USD. Seems ridiculously...decently priced too. But are you more interested in the idol mags or manga mags above?
I remember when I was back in the UK growing up as a healthy young lad - I would go to the newsagents to take a peek at page 3 of the Sun newspaper.
Are newsagents in your neck of the woods filled with hanky panky, erm I mean health mags?
