I visit Gunbroker more than often and 28 gauge two barrel sets selling under $5600 has occurred more than four times since late fall. Here is one just 10 days ago:

Two others sold at or near $5000 in Nov. or early Dec. They haven't been sold near $7500 for as long as I have been watching the auctions.
