Well, I would say that although you don't want to go to your local dealer, you may look into going to our dealership sponsors at SF (Champion Toyota & Elmhurst Toyota).
On 1 item, I calculated that you would get about 45% off.
If you are a supraforums member, here are the links to those sponsors:

Just mentioning it because many are not aware that they can get parts for less than their local dealership.
If I remember correctly, someone mentioned that even if you are not a SupraForums member, you can still get the discounted prices if you are a SOGI member.
SF is now closed to new members if you were not one already Hopefully with all the updates they will be doing that is scheduled in a couple of days, they will allow new members to join...not 100% sure on that though.
EDIT: or you can do what Steve MK3 suggested. He posted while I was writing so I was unaware of it.
