NO, i believe everything is now to be purchased from within the game.I've had a look through the FAQ's at the start of this thread but can't see a definite answer.
In the past I've looked through the store online here: https://dlc.elitedangerous.com/products/ then bought items, sometimes for ships I'm yet to own - the link is now not working.
I understand that you can buy stuff in-game but will this link be working again? - apparently there are a whole bunch of new paintjobs (even for the cobra MK IV) so is there a place outside the game that these can be seen?
First you have to purchase or earn "ARX", then use that to buy from the store.
