On lolotov I usually just buy the PVP rings for 1250 honor and DE them. I can auction the shards for about 60g. This is about 1g per 21 honor. I found this addon though that has a much better honor->gold conversion method, although it takes time and bag space: http://www.curse.com/addons/wow/honorgold


Go to stormwind, buy old daggers from the legacy weapon quarter master for 105 honor, sell after 2 hours for 16g and change. That's about 1g per 6 honor!

According to my stats, if I'd been doing this all season I would have cleared 22k gold by now.
