At the end of each daily quest session, I sell any greys/unusable items, trade all to my group main except for 10g for flight (Jamba auto-repairs when interacting with a vendor, so that's taken care of) and send it to my bank alt. He then saves it towards the cheapest BoE epic upgrade from the AH (all shammies are getting the same gear, so it's just a matter of what item happens to be the best price ATM). The bank alt is on the same account as my group main, so he can get the cash instantly and send something bought instantly.
