Does anyone know where I can buy the Sonic Miniseries?

For the comic book by Archie, Sonic the Hedgehog, I know they are reprinting the old stories, but the only old stories that I don’t see in print yet are the miniseries. I’m talking about the Princess Sally Miniseries, Knuckles Miniseries, Tails Miniseries, and Sonic Quest. Does anyone know where I can BUY them online. Not look at them illegally like on Youtube or something, I’m talking about buying them at an online comic book store.

Here is the link to the front covers of these comic books.
