Be prepared to request higher selling limits. Ebay assumes you're going to get your BIN price, so those all count against you when measuring your monthly sales limit.
EDIT: You're also turning yourself off, possibly permanently, to a large swath of the buying public. You're basically saying you're spending all this time to list items to target one dude. You may want to complement this with some "loss leaders" like shirts or ties to drive traffic to your profile. Just sayin'.
