Is there a way I can change the price of my listed item? It's an auctioned item and I wasn't able to change the starting auction price therefore I am being offered very low amounts.

Once a listing is active there are some fields you cannot change. You currently only have 1 active listing and it is NOT an auction format. You are getting the low ball offers because you are using OBO on your listing. Simply end the item, relist it and make the adjustments during the relist process. Ditch the OBO.
