Huh? Artifact Authorization alone costs, iirc, 2700 CC for the entire account. Hide Head slot, 1-2 additional quickbars, 2 or more character slots to store my credits on (wait...they are on sale, aren't they?), maybe some inventory slots? I'll have a look. Maybe the 3rd crew skill? Don't see much value in it, though. Haven't done any crafting so far.
The rest of the store is utter trash. I am not stupid enough to waste my CC on online scratchtickets. The stuff is downright worthless. Most of the items is stuff you'll never use and selling them does nothing anyway as your credits are capped at 300k and there's nothing you can spend the money on anyway with the cap.
/If/ there was good stuff to buy at the CM, I would gladl throw my money at Bioware. The unicycle mount for 10-15€? Sure, have my cash. Take it. But spending it on a scratchticket? Monkey business.
