The 256gb 15" is on sale on amazon with 150$ discount. Also remember that you don't pay tax in some states, so if you're in any of those states you save like 400$
Honestly, I am certain that it will be bested, just keep checking over these next few days. Check ebay and CL if you're inclined. I would also keep an eye on the Apple refurb store, I would expect some good deal to show up there within 7 days.
