I'm inquiring about the final pricing in AUD for your small crawler tractors equipped with trenching arms and auger drills. Specifically, I need the total cost to include all relevant fees for delivery to Adelaide, South Australia. It would be great if you could break down any additional charges and confirm if there are any discounts available for bulk orders or repeat purchases. Additionally, please provide an estimated delivery time for the tractors. I'm eager to understand how long it typically takes from order placement to arrival. If you have any insights on tracking options or shipping methods, feel free to include that information. I look forward to your prompt response so we can move forward with this potential order.
