For deputies I'll ask a lowbie halfling to vendor spears for me for a cut of the plat. Never ran into an issue across multiple characters/guard camps. I'd rather lose a little plat than have to worry about losing the camp while I go sell. 10p is plenty of a tip per bag, especially if you let them know you'll need help throughout the day.

For treants, bind at centaur village and buy then resell a gem to turn the gold/silver into plat. Its not a bad idea to keep a stack of peridots on you for doing this. You can always kill the merchant to reset its inventory and sell/buy back the peridots, he's only ~30.
