Here's the thing, you don't need to own all of the champions and/or own twenty entirely unique rune pages ever. Unless you get to challenger all you need is about 10-20 champs who you can play decently and 2-5 rune pages, in which you will repeat runes, making it cheaper than you thought. If you want to get 20 rune pages and own all of the champions, great, be a completionist, but it is never necessary. It's much more doable to get a few champions that you are good at than to buy all of the champs, some of whom you hate.
