Act as an e-commerce manager focused on catalog profitability. My store sells niche on platform or marketplace. I will paste a product list with name, selling price, cost, units sold in the last period, units sitting in stock, and return rate. Analyze the catalog and tell me what to do with each product. Follow these steps: 1) Calculate unit margin and total margin per product, and show the math you used. 2) Sort the products into four groups: drives revenue, drives profit, breaks even, and ties up capital. 3) Recommend one action per product from promote, keep, reprice, discontinue, and clear out, with a one-sentence justification grounded in the numbers I gave you. 4) Point out the products that look like good sellers but return little once returns and shipping are subtracted. 5) Suggest which products belong in a bundle, and what to bundle them with. 6) List the data I did not provide that would change your recommendation. Present a table with these columns: product, unit margin, total margin, group, recommended action, reason. After the table, write the five most urgent decisions ordered by cash impact. Do not invent numbers I did not provide, and write "missing data" where information is absent. Use currency. Catalog: paste here
