U can do much i mean much quicker then above 2 ways.
Just pick under jedi tab the jedi knight robe they sell for 7700credits each.
When full inventory look for closest junkdealer and sell all till u got atleast 1 item left and keep ur junkdealer window open.
Go back to the frog click fast till inv is full again and now u can stay there while selling the robes
U can also respec to smuggler and bring the personal junkdealer up.
So others can sell on urs plus u get an credit bonus when u store the junkdealer.
