SWTOR, Collections And Your Account

I found myself wondering today about how Collections work for SWTOR. You can access your Collections interface from the Collections button in the Cartal Market and Inventory screens. For items that are purchased, and bound to a character; those that qualify for addition to your Collection can be pulled from the Collection for that character ad infinitum. Further, the item will appear on other characters with the option to unlock it Account wide with the same benefit.
