So, the 60 spirit water pack isn't actually 20% cheaper unless you buy 60 spirit waters one by one at 100 gold per water. If you do the 9 + 1 packs for 900 gold, multiple that by 6 to get 60 spirit water, that'll cost you 5400 gold.

So compared to the other lowest priced spirit water/remedy pack you can get it's only 11% cheaper. (And you save 600 gold, which is enough for two rare summon attempts.)
