I guess OW has price-matched AmazonAU for the mac mini M1 8gb/256gb
($82.90 cheaper than Edu pricing)
You might be able to get OW to price-match the 8gb/512gb version for $1139.05 as it is $1199 on AmazonAU
https://www.amazon.com.au/Apple-Mini-chip-8%E2%80%91core-512…
(AmazonAU price gone up to $1204 for 8gb/512gb version; so $1143.80 if price-matched at OW. [$122.30 cheaper than Edu pricing]).
I have an old 2013 iMac, could I buy this Mac Mini and connect it to the iMac as a monitor??
