I just ran some trial sales thru Monster Mill's website and came to the interesting conclusion that the mills come to A$125 and some cents each delivered to Aus when ordered in pairs. I also noted that total postage (US$38) did not increase when I ordered three or four mills. Seems to be cheaper to go straight to the source.
Frankly for the sake of $5, I'd save the bulk buy co-ordinator the trouble of ordering and just arrange this amongst ourselves. You Melbournians could do well out of this. Total price for 4 delivered to the same address is US$434, which according to www.xe.com/ucc is currently A$460, or $115 each. Is there $5 worth of fuel between your houses? Does PayPal have the same conversion rate as xe.com? If the answers to those questions are "No" and "Yes" respectively, then we're wasting our time in here.
Frankly, I would expect MM to have offered us a genuine bulk buy deal, not just offer split postage, which is available to us anyway! And that would be using the very convenient PayPal rather than the "Wire Transfer" service that MM is suggesting.
I'd like this to be wrong. Someone show me where I'm wrong!
EDIT: Just for a lark, I put in an order for 40 mills on their ordering system and shipping (using PayPal) still came to a flat US$38. Not our fault if the site calculates shipping wrong is it? Under good ole yanky lawz.
