# MK-080 | Core-product positioning

For a regular chat, upload `packs/mk-080.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **The role of regular products that can be sold continuously**

Products occurring in the same transaction do not establish psychological motives; a product pairing does not automatically prove cross-selling effectiveness

## Required inputs

Provide: SKUs, product costs, customer groups, purchase records, and product lines

## Method

1. Core products are the brand's most important and representative offerings, supporting full purchases and member benefits after traffic-driving/trial products
2. Make the next main purchase option clear to customers who already trust the brand
3. Pricing still requires balancing the market, audience value, and costs

## Calculations and interpretation

Product selections and next-need proposals are candidates; check inventory, gross margin, existing buyers, and sales data

## Required output fields
