I dont want to seem to be ignorant but I am one of the worst when it comes to saving money in games, however this one I am not having a problem. Here is what i do and what may help you out if you are broke. A little background first I have two 50's a 41, 34 and 36 so far. I have all the crafting professions between them (make my own everything for companions) pretty much and use the commendations for my actual toon's gear or mods. just by questing on my powertech for example vendoring all loot and putting blue, purple or custom loots on GTN I was able to have all mount training, mounts and still have about 400k in pocket at 50. Marauder was different story he died a lot leveling so spent most on repairs..lol. This is what I do when I need cash or want to increase amount, I run 2 flashpoints Mandalorian raiders and foundry solo it doesnt take too long and you will clear about 25-30K per run, also hit the mid level daily heroics 34-40ish area, these can easily be solo'd by anyone and you make decent return with loot/turn in cash, I hope these ideas help some of you that are having money issues because i know how frustrating it can be.
