Just to illustrate the disparity the Australian consumer faces:
You list an ER32-MT3 chuck with 9 ER32 collets (about half a full set) for about $260 + postage say $275
A quick flick to Ebay, without trying to find the cheapest seller
ER32-MT3 chuck with a full set (19) of ER32 collets $150
(and I have deliberately taken listings where I pay for item and pay for postage)
Brand NEW ER32 MT3 M12 Morse Taper 3 ER Collet Chuck Holder CNC Milling Lathe | eBay
NEW 19 PCS ER32 Spring Collets SET Range 2mm 20mm ER32 Collet Chuck CNC MILL | eBay
that is almost half the price.
I know that you will say that your items are better quality than the Ebay items, but I actually have those Ebay collets and they came in the same little boxes shown on your (vey small) picture and they are excellent.
Now, I assume your reference to "our lacks government" refers to the vexed issue of GST on overseas buying, so let's add the 10% GST to the Ebay order.
That makes it $175, I would still be $100 better off, and I would have a full set of ER32 collets as against a half set.
