I've been keeping my eye on the refurbished Mac Store for a while but I haven't seen a Mac mini on there, do they ever go on sale?
+1 on using Refurb Tracker. That’s how I snagged the config I wanted. Ten minutes after I received the email and placed my order, they were out of stock of the config I ordered.
I have a 2012 (also refurb) and decided it was time to upgrade.
I just noticed that, I signed up and they had the config I wanted, but only saw the email an hour later and they were already out. Gotta move quick.
