Well good news is we had the BEST IDEA for the shopkeeper.
Our idea is:
Make the shopkeeper into an uberboss, and if you manage to kill him, all of the items are for free. Excluding potions. Those are gone forever.
To initiate the battle, you have to anger him. Ten hits with a sword will do it. After that, he grows.
Really big. He requires 1000 hits from a SWORD (not ranged weapon) in order to kill him. He does 100 damage, so you NEED armor to kill him.
The perfect uberboss c:
