I actually schedule 30 mins at the end of a long session or end of the day to check on my pots/ scrolls/ wands stacks to make myself more self sufficient for several reasons:

1) My healbot cleric, Faithrune wants to roll up in the corner and cry her pretty green eyes out when someone dies under her watch. (so she uses SP for the party and pots, scrolls on herself)
2) My Paladin Heidiann, feeds Faithrune so knows the costs of clericing and always has stacks of pots so the Cleric on her quests can help in this order a) themself b) the party c) Heidiann
3) The Squishy Sorcerer Shamurai is in the back but can still be two shotted by so many things so yeah... Can't always risk that the Cleric will notice and be was told by Heidiann that "Caring for the Cleric = Good Thing"

I am sure as I get better I wont waste as much as I currently am, by over potting or over stocking, but until then I want to be an asset to the party not just another soul stone to lug to a shrine, or spell point dumping ground.

~ added benefit.. if you give one of your pots to a party member.. perhaps they can pay it forward someday. Kindness is a seed that's worth planting, and has endless potential for growth.
