Fallout 3/Collection quests

There are some characters that want some items scattered throughout the world. For getting them and bringing them to the appropriate person, you get either caps or another item in return.

Bloodpacks

You get a karma bonus for donating to churches in Megaton and Rivet City.

You can also invest bottlecaps to Uncle Roe in Canterbury Commons to improve the quality of goods and repair skills of the travelling merchants.

Bounties: Fingers and Ears
If you have the Lawbringer or Contract Killer perk, you can travel to the place identified on the note you receive (and shown on the map) to obtain a reward for each finger or ear. These items are located on the corpses of either good or evil characters in the wasteland.

Brotherhood Holotags
Bring a holotag from a fallen comrade from the Brotherhood of Steel to Scribe Jameson. She will give 100 caps for each tag.
