Here in Paris/France there are still lots of computer shops too like you in Australia
Once around year 2000 there was a big hypermarket for computers stuff (called Surcouf) but soon lots of independants chinese little shops begin to appeared around it with better prices
Then the hypermarket close down but the chinese shops are still here: in fact now all the shops are now only in a single street facing the metro station: it is Rue Montgallet

We have a comparator at
https://www.rue-montgallet.com/
so can find the best/price availability so only need to go with the metro and you get your stuff in 1 hour
The shop where I have first seen an Amiga 1000 still exists at Paris too but now it sold mangas, consoles, anime figurines, etc...
