Vend, use exchange, fish, pick up trash, or play zOMG! and sell your loot from that. Secret to zOMG! is that the gold grants may be little now, but thanks to inflation the loot has inflated quite a bit. Like a common recipe I'm able to sell for 9K gold now. Not much but every little bit helps. If you are able to make and craft mint sundae in that game, you can sell it for around 20 million gold.
