Crystal Healing and Mana Potions are purchasable consumables from Ogri'la which are significantly cheaper than Super Healing and Mana Potions, but are equally effective.

Currently all consumables of equal efficacy are weighted identically, so the location of the items in your bags when buffet scans determines which is selected to be used in the macro. Due to the cost difference, this is likely not the desired usage.

Similarly, Potion Injectors suffer from the same issue where bag order determines use, and any fix implemented to prioritize Crystal potions could be applied.

Injectors should be prioritized since version 2.5.1.81_Beta
I should be able to made "Crystal Healing and Mana Potions" using the same trick, I just need wowhead link to the items and/or their IDs.
