Strictly Profitable

 refers to an unmarked and repeatable quest in Fallout 3.

After receiving the Mesmetron from Grouse in Paradise Falls, the player has the option of enslaving NPCs other than the four VIPs required to complete the quest Strictly Business. For every slave the player captures and sends to Paradise Falls, Grouse will pay out 250 caps and give a new Slave Collar to continue the "recruiting." He also sells Mesmetron Power Cells at the steep price of 200 caps for 10 rounds. It's possible to offset the high price if all 45 rounds he initially gives out are carefully utilized, since he also pays out caps for turning in the VIPs.
