How often do merchants replenish their gold supply?
How long does it take before a merchant replenishes their gold supply once I've cleaned them out? I've tried waiting for a 24 hour period and that didn't do the trick. I've also attempted to leave the zone and come back, which also didn't work. Is there a trigger for the refill? Or is it just a specific amount of time I have to wait?
Actually in Oblivion I'm pretty sure that they don't lose gold. That's what happened to me at least on PC. Might have been a glitch.
No, you are correct. In oblivion, the 'available gold' was more 'maximum amount of gold the merchant can pay for 1 item'. He could pay the same amount for the next item, or the 100 items after that. Skyrim *fixed* that.
One thing to note is that merchant gold *and inventories* respawn after a quit to desktop. This is handy if you're making rounds selling to every single merchant in a town and don't feel like fast travelling across the map for whatever reason, and is especially handy for 'farming' items such as, for instance, filled soul gems from the various merchant/trainers in Winterhold.
