You might consider this Nikon E plan set.

By the time you pay for each of the Chinese ones separately, you are into more money and it would be luck indeed, if they performed as well. Emma Chisit fer shippin? It is showing me 10.00 to Australia, same as to here( Canada).

apochronaut's advice looks like a good deal to me.

+2 to Phil's advice. The Nikon Plan objectives are very good. The seller is reliable. They're at a good price. And because they are "chrome free" they can be used with either Nikon eyepieces (CFWN 10x/20 suggested) or the generic imports (10x/20 WF). They don't require correcting eyepieces, unlike many other used sets you might find.

I've used a couple of the import types shown. I'd rate the 20x I had as about as good as a bottom end Olympus Achro (not plan) and not as good as a DPlan. My example of a 40x wasn't as good - but it came to me used.

If you want a full set, I'd jump on that listing before someone else does. You'll also have the option, should you later choose to be extravagant, to find affordable Nikon replacements in CFN (some fluorite glass) or Plan Apo ($$$ even used, but about as good as it gets for a hobbyist).

I have recently compared a (used of course) black Optiphot Nikon 4X0.1 Plan objective with a new non-branded 4X0.1 Plan objective. The Nikon wins hands down.
