How is this report measured?
This is a frozen report of stock periods that started during this reporting week. Restocks count product-and-location events, not units sold or every Costco transaction. Repeated stock periods for the same product count separately.
Premium compares the recorded purchase price with the spot value of the product’s metal weight. “Lowest recorded” is the smallest observed premium during the period. The full stock duration is measured from restock to sellout; a best-premium buying window needs its own timestamp and is shown on product pages.
Modeled returns apply 2% card rewards plus 2% Executive rewards and a dealer payout 0.65% below the recorded spot price. They exclude fees, shipping and tax and do not establish a historical dealer offer or completed sale.
Missing enrichment is omitted rather than counted as zero. Availability can change between observations. Gold Alerts is independent of Costco Wholesale.
