How do I buy mangas digitally?

Is there an easy way to buy them digitally?

I don't want to run the risk of losing all the series if the current big sites close down... so buying them digitally would be at least way more secure.

I'd suggest going to the publisher like Dark Horse or Viz and there should be an option for you. I think you can also sub to Shounen Jump and Crunchyroll

Also the best and most secure way to own manga is to own physical copies, unless you download everything and make backups

Does subscribing to Shounen Jump also give me access to all the old mangas?
