I would recommend skipping the expensive, high end trekking poles. Rummage around and find an old mop handle or similar, rig up some sort of lanyard, and you have saved a bunch of money, t no loss of utility. You will hardly notice the added weeight, the pole is swinging from your hand.
The one benefit for collapsible trekking poles is that they can be shortened to be easily stowed in luggage or your pack. Of course, their purchase does prevent unused cash from cluttering up your premises.
one or more gifts or other benefits from the co-op.
