This document provides instructions for editing product prices on the Paytm Mall catalogue in three ways: individually, in bulk, and general pricing guidelines. It explains how to edit the maximum selling price, minimum operating price, and individual product prices one by one through the catalogue interface. It also outlines how to download a CSV file of product prices, edit prices in bulk directly in the file, and upload the updated file to change multiple prices at once. Finally, it mentions limits on price increases/decreases and sample error messages that could occur.
