# Get a product set as sale line items

> Returns the set expanded into the exact payload shape `POST /sales` expects for
`items[]`, with server-computed totals, so a set can be applied to a sale without
the client re-deriving the mapping. `staff_id` is left null for the caller to fill.
Each item also carries an `itemable` object (`{id, name}`, same shape as a sale
item's) so line labels can be rendered without a second request; it is ignored when
the payload is posted back to `/sales`.
