Okay, I may purchase two rackets worth $179 each right. I checked and it's $41 delivery, now first off is that for each racket, or separately? Now, does delivery of the shirt cost any extra? Also does the 6 pack Wilson bag (http://www.tennis-warehouse.com/descpageBGWILSON-WKFED6.html) cost $20 including postage, or is postage additional. I am in Australia.
