Take whatever Gander Mountain has it priced out at, multiply that by zero point seven five, and that's about what it should sell for in the real world.
ETA: Point being, when it comes to retail gun prices, GM is not "the real world." They are a world unto themselves. Beware.
They are used pieces, which GM _may_ have reasonable prices on, or even the occassional deal. I stop by the local GM at least once a month to check their used guns. They used to be in-line on pricing of "basic" guns like .22s and 870s, but now those prices are just as ridiculous as the rest.
I have purchased two used guns from GM at reasonable prices - a lightly-used NRM Colt Commander for ~$600 and a used Winchester 1300 Defender for ~$165.
ETA - That said, unless those 92S's are damn near pristine in every way, they are WAY out of line. A NIB 92FS will go for $550-$660 these days, and I haven't heard of anybody ever seeking out a 92S specifically - and with import marks (I'm assuming _recent_ non-Beretta markings), it's not exactly a collector's piece anyway.
