For whatever reason the price for Ultima Replenisher (90-serving
canisters) got jacked up, big time. We used to pay around $25 in bulk,
now it's around $40 with shipping. We go through a lot.

Are there alternatives of comparable quality but more reasonably priced?
Orange flavor would be great but doesn't matter much, as long as it's
not any funky or excessively sweet flavor. No artificial sweeteners.

Buy 25kg of coconut water powder for $395. Enough for 1250 bicycle water
bottle fills, at 20 grams per bottle. About 32 cents per bottle.
