Ironically, paying for bombs is a deterrent for me. It's convenient to ppl who come through just to buy bombs from folks who DO have vendors at their house - the inconvenience of going to a random bomb / arrow store is minimal.
I don't ever use them myself unless I'm building something and need to test it out.
Generally I will only ever farm if I have 99 bombs from killing bandits or pyrats or lizardons.
:/ But 12k worth of my furniture disappeared for no expletive reason... That's theft. Right up there with all the other crap that's been perpetrated lately...
