澳大利亚采购需求：赛车轮椅，碳纤维GPX赛车轮椅，管胎，TUFO管胎，TUFO管胎赛道轮胎，可调节拐杖

I'm looking to get pricing information for both sets of the products I'm interested in. Can you please provide the total cost and also let me know the shipping options and prices for sending them to Australia? Additionally, if there are any discounts available for bulk purchases or promotional offers, please include those details as well. I'm eager to move forward quickly, so a prompt response would be greatly appreciated. Thanks!
