"yes."
Well that person left an extremely helpful answer there.
There is a way that involves using the vendor glitch, you may or may not consider this actual "cheating".
Look for a weapon or armor vendor, as this involves the armor/weapon condition affecting the price the NPC is selling the item for.
Choose any item he has two of. Normally he'll have a more expensive one that is in better condition and a cheaper one that is nearly broken. Buy the cheapest one, the nearly broken one, and then sell it back to him. Buy the cheapest one again and it should have repaired itself and now sells for full price (sometimes you have to repeat the buying the cheapest selling it back a few times before the item in your inventory updates to full repair and you can get the highest money for that item by selling it back to him).
It's also a way to get a free repair on any item you have as long as the vendor at least has one of that item. If he has one and you have one you can sell him yours and do the buy cheapest sell glitch to get all of the vendors money. Then you may buy anything you like in his inventory and not break the bank!
You may consider it cheating to use this glitch, and then you may just decide to put your points in barter when leveling up to get better deals without the glitch.
Hope this helped better than the Yes there is one answer :/
bottle caps
In my opinion Fallout New Vegas is. In Fallout NV it is easier to make caps so you can buy better wepons and ammo. In Fallout 3 It's hard to make a lot of caps in the begining making it a slow start. But is you want to test your skills play Fallout 3.
You can sell your stuff. Or you can kill people to get it. :)
You can kill people and steal their stuff, and sell them. :)
You need 50 Sarsaparilla Star Caps to proceed to the next part of the quest.
because there more common than normal paper money
In the post-apocalyptic world of Fallout, bottle caps are highly valuable as currency. They are widely accepted and used for trading goods and services, making them a crucial form of currency in the game's economy.
Sorry, but there aren't any "cheats" in Fallout 3. There are, however mods for the PC version but that is all. Also, there are glitches to get more caps and such that can be counted as cheats if you want.
No, but you can sell them for caps, and it has no weight; so you can hold as many as you want.
Take them to the Regulator HQ and they will give you a regulator duster and some caps for every finger you bring them.
She is a hooker but does nothing but sleep does not provide any bonuses or active effects not worth the caps.
its pretty easy just keep killing raiders, scavengers, raid places, and loot everything.
