9 quarts of new, unopened 5W-30 motor oil - $11.99/quart retail, would be $108 total but will split the difference and sell for $50!

One box of 6 unopened, one box opened with 3 bottles still sealed/new/unused

Has been sitting in our storage room for 2+ years, could return to Costco for a credit without receipt but I respect the American institution of Costco too much to do that to them or my fellow shoppers
