Where can I find a tree house for kids?
I don't think you can find one that is already built, what you can do is buy your own wood and build it at home. Or you can shop online for more specific things from @Ubuy Jordan
Where can I customise my af 1s?
I think you can do that through @Nike 's online store, though I am not sure if they ship to Jordan.
Where can I find affordable beef slices for yakiniku and shabu shabu?
Honestly, if you need good quality meat its better if you stay away from cheap prices, but I would recommend @The Meat Master
