Thanks. Does a product name work too?
Yes. A product name or a barcode photo returns the same answer.

Left: from a barcode photo. Right: asked in words. Suppliers and amounts are masked.

A pile of denim and a barcoded price tag (photo from the floor) — This is the tag staff photograph on the floor. Barcode and number are masked

What else it does

From a photo of the barcode (JAN) tag it returns supplier, unit price, shipping, quantity and purchase date
Plain language works too — “all Carhartt costs” returns the latest landed cost and past purchase prices for each matching item
