Is there a complete list of all the Account Wide C-Store items? Ships, Bridge Offs etc? Im not sure if i would want to buy a Ship or Bridge Off with real $ to have them trapped forever with just one character.

Not sure if there is a list but ships, bridges, and uniforms are account wide unlocks. Pets, Bank/personal inventory, Doff roster increase, any of the services(rename, respec, xp boost, ship slot, Boff slots, etc) are single char only.

I think this works as a rule of thumb: If you didn get it before Season 5, and it dosent say in the description, it is not a Account Wide unlock.

It should be noted that the website version of the C-Store is more explicit regarding these details than the in-game version of the C-Store. All items feature a text description, appearing on the right-hand side of the screen, which indicates whether or not the item "will be unlocked for every character on your account" or will be purchased "for this character." There are many items, including ships and costumes, which are still available as account-wide unlocks.
