Did you see how much effort it was to take the zora kid to kakariko? And once they get there, what are they supposed to do? There's probably minimal food, lack of things to do and dust clogging up their lungs.
I don't get any magazines anymore. To expensive for what they are, considering you can get everything in them much faster on the internet.
I read NOM a few times though. It was alright. I got the first issue of ONM and it was shit.
You can try ringing everywhere, but that takes a lot of effort. Try waiting untill january or february when most places should have them, or if that's too long, ebay or amazon marketplace. The prices are starting to drop now anyway.
