Other stores selling it
Coreplex counts another store's listing as the same item only when it shares a Shopify catalog ID or barcode with this one; lookalikes are shown as similar and never priced as equals. The live page runs that check now. AI agents can run it with the Coreplex MCP tools get_passport or compare_prices (product_url: https://www.optimumnutrition.com/products/essential-amino-energy-pre-workout-powder).
