If you can herb, Swiftthistle brings a nice price on the AH. Is mining your thing? Copper bars and low end gems are snapped up on the AH by people leveling up Jewelcrafting, Engineering and Blacksmithing. Do you just kill humanoids? Well then, Wool Cloth has always been profitable for bringing up First Aid, Tailoring and factions in the major cities.
Though, honestly, going out and questing for half an hour at any level will get you enough money to buy supplies and pay for repair bills. So I just don't get it. Isn't playing the game more interesting than standing around asking for other people's money?
I am really baffled here. Do you beg and if so, why? If not, why do you think people beg?
