storage question

Hey ive seen some people saying things like selling 100+ items an such. and i was wondering where they keep those 100 items? is there a possible way to expand your storage or is there something else needed. Know this might be a nooby question but i need answers

On other characters and second/third/fourth accounts.

Yep. If someone has Proph and Factions he gets six character slots. Fully decked out with pouch and bags, each character can hold up to 45 items in their inventory +2 in their hands, as well as the 20 slots in their storage.

Thus a player can have up to 302 items in one account.
