The issue with the lighters is that their charges are worth $1.20 each, not the lighter items themselves. You need to fix the charge's worth to fix #39945(you have the wrong issue linked in summary).

By my understanding of the bartering system what i have done is correct although feel free to correct me:

From Item.cpp more accurately item::price a tool which does not have have ammo which a lighter does not has its value reduced proportional to the number of charges (So if it had a value of 100 but had 5/100 charges it would have a true value of 100 * 5/100) by changing the value to 60 the value of a lighter with 1 charge would actually have a value of 60 * 1/100.

However from npctrade.cpp the value you sell for is changed by 0.05*(Seller Barter Skill - Buyer Barter Skill) which gives $1.20 in the issue.

By my changes the values become:

which is the expected values

This is still a lot, with 100 charges a player should be able to sell a lighter for about 10 dollars not factoring any barter bonuses, considering the refillable one is about 5 dollars filled with 50 charges.

[TartarusKelvin]

New updated price is $0.10 per charge so a full lighter should sell for $1.00 before barter bonuses

$1.2 is probably overvalued but it's not grossly out of whack.
