Last week I ordered the following telescope bits online:
1. a primary mirror from the US.
2. a red dot finder scope from Hong Kong
3. a mount for the finder scope from Hong Kong (different supplier).
4. a collimation tube and 2 lenses from York Optical Australia.
Items 1 to 3 turned up this week to my local PO in rural South Australia.

Item 4 has not only not been delivered but the supplier has failed to answer three Emails enquiring about the order status.

It's sad that so many Australian suppliers in all fields just don't get it when it comes to customer service and are thereby contributing to their own demise.
It's a world that we live in. Ordinary people can now order goods from anywhere in it and very often take delivery of those goods within a week.
I know where my next online orders for telescope components will be placed and it doesn't start with 'A'.
