You can get the Apollo 8 (original or updated version) at a discount on the grey market, like C24. FOIS are still at MSRP. Don't expect any discount at an OB.
FOIS too new for any discounts. DSOTM Apollo 8, much bigger discounts on the gen 1 than the newer. If you search around, you can get the newer Apollo 8 for about 12.5 to 13.5
