GoldBoxing(tm) at 80 is a joke.

Between dailies, quests and the superfluous amount of gold that farm raid bosses drop, I can't spend it fast enough. I just spent 24k on a set of Grand Ice Mammoths on Friday, and have already accumulated 6k since then.

As for gold while leveling, don't underestimate the value of the stuff you loot. Lowbie materials sell for what is a relative fortune. 10g is nothing for me to spend on a stack of cloth if I'm leveling a tradeskill, but if you sell 10 stacks, problem solved.
