Paul.....we have the same published extended shipping times...say 25 to 45 days for delivery in Australia
I believe, the Chinese Government support 'free air parcel post' for a $2.50 parcel of goods
It appears that the hundreds & hundreds of customers individually sealed parcels of goods are sent in one consolidated air freight shipment to an address in a suburb in Sydney [Australia] then individually re-posted via our Australia Post to the recipient's address
It all depend on the fortunes of timing
...I have received small parcels of these M3 brass nuts & washers in 4 days, then waited the full 45 days for other parcels of the same/similar ordered a few days later
I find the experience of buying & repeat ordering via E-Bay from these Chinese suppliers absolutely 100% in terms of quality & as quoted delivery
