Pre-order weapons always there?

Are pre-order weapons always there? If I get a pre-oder weapon for my PVE character [by typing /preorder, right?], can I trash the weapon and type /preorder again to get it back? Or will I only be able to get my pre-order weapons only once per character?

Is this the same for both Factions and Prophecies [Ithas Bow]? Thanks.

They're bound to your account. You'll never lose them forever.

You can toss the weapons as many times as you like on one character and type /preorder to get them back (while in a town or outpost).

Same applies for Factions and Prophecies pre-order items.
