There’s also a way of “emulating” classical distros in Arch / 
, by downloading full Arch repo + aur packages that you really need (let’s say you have a friend or access for super-fast internet elsewhere) once per month, 2 month, half a year or whatever…
Just bring it back home on some flash-drive or small hard disk, update system from local repo copy and install software only from that local copy, whole repo is not as big as you might think…something like 30 Gb.
The only downside of that, and skipping updates the way mentioned by @r0ckhopper is that you will skip security updates as well, until doing full system update which is not optimal…
