multipack
The number of identical items sold as one unit. A six-pack of socks has multipack: 6. Channels show this so users know what they're getting — and the GTIN refers to the pack, not the individual item.
Also known as: pack_count

Why it matters
Multipack items confuse channels and users alike when this field is missing. A 'pack of 6 socks' priced like a single sock looks like a pricing error; the same pack with multipack: 6 set explicitly contextualises the price.
The multipack field disambiguates "this is one item containing N units" from "this is N separate items". A six-pack of socks priced like a single pair looks like a pricing error to channel classifiers and confuses users about what they're getting. Setting multipack: 6 makes the structure explicit: one transaction, six items inside.
The field interacts cleanly with GTIN: the multipack's GTIN is the multipack's own barcode (not any single component's). When the GTIN is missing because the multipack hasn't been assigned a unique code by the manufacturer, identifier_exists: false handles it. The fields don't conflict — multipack describes the unit composition, GTIN describes the unit's market identifier.
Distinct from is_bundle (which handles mixed-item sets), multipack is for identical-item sets only. A six-pack of identical socks is multipack: 6. A set of shampoo + conditioner + soap is is_bundle: true with no multipack. The two fields are mutually exclusive — using both on the same item creates a contradiction that channels reject.

What's the difference between multipack and is_bundle?
Multipack = multiple of the same item (six identical socks). is_bundle = mixed items sold together (shampoo + conditioner). They're mutually exclusive.
