Somethings can't be applied in the store ... like shaman energy (you apply at the shaman) ... domain guards (you apply on tile on the map) ... Great Relocations (go to ek to apply) ... torches (apply at the building) ... time boosts (apply at the upgrade you want boosted ... etc.
You might find that those showing in my items may have already been used.
When you can add charms you will see an arrow pointing up on the hall of mysteries, opening up the shamans page directly, or indirectly, shows you which shaman you can upgrade.
Clicking on the shaman with an arrow automatically adds them.
When I bought Baggi charms from the clan shop , they seemed to be added straight away, rather than being saved for later, but this might have something to do with whether or not the stage is open and you can add charms.
