You can maximise a sale by wearing the Roving Trader Hat and Clothing (+5 to Barter with each = +10 Barter overall) and reading a Salesman Weekly magazine beforehand (+20 w/Comprehension). This will max the caps gains you can make when you sell. 9mm Pistol can repair a 10mm Pistol/9mm SMG/10mm SMG or the. At this point you can use other weaker and less expensive weapons to repair these weapons you have collected (e.g. When you reach level 14 take the Jury Rigging perk (need Repair 90). don't use a 10mm Pistol to repair another 10mm Pistol). Whenever you collect one of the above weapons NEVER use one to repair itself (i.e. Also collect every other weapon you can find to use with Jury Rigging. They are also middle range weapons (there are better versions) so you shouldn't miss them if you sell them.

Vault 3 can be a very good place to horde some of these weapons. These weapons are not too rare and many can be found on Humanoid enemies like Powder Gangers, Super Mutants and the various 'Raider' gangs. The prices indicated in brackets are when these weapons are near 100% condition. Try to get the Bartering skill to at least 50 as you level also.Д¬ollect the following weapons on your travels and keep them in a safehouse until you reach level 14: The Comprehension perk can also help to temporarily add 20 points of skill for Repair and Bartering with their respective magazines (and many other things too). Be sure to collect snowglobes on the way, the ones at Goodsprings, Lucky 38 Casino, Vault 21 and Old Mormon Fort are easy to get, and give them to Jane in Lucky caps each (these do not contribute to the achievement). I suggest raising Intelligence to 7 at Character Creation and racing to New Vegas at the beginning (avoid sidequests, do main questline) to get to the New Vegas Medical Centre and purchase another Intelligence point implant at low level (giving 1 extra skill point at levels). The Jury Rigging perk can help repair expensive weapons with inexpensive weapons, maxing cap gains.ДЄt the beginning of a game Tag the Repair skill and as you level pour skill points into Repair to get it to 90 ASAP. Boost your repair skill early (which is always wise) and repair and sell weapons for high gains. I recommend you use the old Fallout 3 Repairing Trick.
