Overview

Runs a retailer price/stock probe for a Costco catalog item.

This is the Costco-specific replacement for the generic Oxylabs
scrape-and-extract pipeline. Costco's grouped products have no
per-variant URL, so a rendered scrape can only read the page-default
variant. Instead this probe calls CostcoApi, which is keyed
by the item's Costco item number and returns accurate per-variant data.

Both PriceChecker (realtime "Probe Now") and
BatchPriceChecker (scheduled runs) delegate Costco items
here, so all probe bookkeeping lives in one place.
