Refurbished…
Denon has, right now, the x4700 refurb for $1499, x3700 $999, x2700 $699. All refurbished.
Onkyo has the tx-rz50 refurbished for $1119, tx-nr797 $699, tx-nr6100 $639, etc
Pioneer has the vsx-lx505 for $1199, vsx-lx305 $999, vsx-lx504 $799, vsx-lx304 $639
They don't stay on the sites for long.
PS: To me manufacturer refurbs are better than new. They have been throughly checked and fixed whatever it was before selling those returns.
