Sunday night I decided on getting the 16" MBP and the 2.3ghz 1tB model I coincidentally wanted was in stock at the refurb store. But I needed to figure something out with a trade in and had to talk to someone from apple first. Called in the morning, got it all sorted out, and when I finally was ready to order they were gone and haven't been back since.
Luckily, I was able to get the computer new for the same price as refurb off an Ebay store. But the refurb would have been better. I would have been able to use Rakuten's 2% cash back when buying and also been able to retroactively credit back the apple GC I get for my trade in to my purchase once that process wrapped up. Ah well.
