I've just recently thought that it would be sooooo awesome if I could support the mangaka or publishers of my favorite series directly. This is since most of the manga I read are unavailable for me or most cost goes to shipping..
If there was a chance to donate directly people like me could show their support another way

Maybe it is a stupid question but is there any chance to do so>?

I'm not sure if I wanna do this

As far as I know there is no way to direly donate to mangaka or publisher.
However if buying a book, but avoiding shipping is good enough you can always buy digital manga. There's a surprisingly big collection of titles out there available for digital sales. And you can support both mangaka and publisher with it, on top of that you get the manga as well.

Personally I'd suggest ebookjapan because of their image quality. If you'd prefer buy to own option I'd recommend dlsite, however this site is specialized in selling doujin content aka a lot smaller collection of major published titles, and those tend to be DRM protected so reading is limited (and bind to internet connection so your identity can be verified).

I hope this info helps, on how to buy google for tutorials there's quite a few out there.

Another good digital site to buy English ebook manga is Renta.
