# Ship every order in the cheapest box that fits > You get a packing chart anyone can follow, with the cheapest box and total cost for each common order. List your products and the boxes you stock, and get a simple chart with the cheapest box for every common order, so packing stops being guesswork. - Page: https://thesolocreators.com/prompts/cheapest-shipping-box-for-every-order/ - Category: Make smarter decisions - Made for: Small business owners, Creators - Works in: ChatGPT, Claude, Gemini - Time: About 15 minutes - Effort: Just copy and paste - Published: 2026-10-29 ## How do I pick the cheapest shipping box for each order? List your products and the boxes you stock, then ask ChatGPT, Claude or Gemini to work out the cheapest box for each common order, counting box and postage together. All three handle this as a single paste. If you ship only a few products, a chart for single items is enough. If customers often buy two or three things at once, ask it to cover the most likely combinations too, plus a backup box for when one runs out. ## The prompt Fill in the parts in [square brackets], or leave them and the AI will ask you for them. ```text You're a shipping and packing expert for a small online shop. Help me stop wasting money on boxes that are too big. My products, with size and weight: [YOUR PRODUCTS, e.g. mug 12x9x9 cm, 400 g]. The boxes and mailers I stock, with inside size and cost each: [YOUR BOXES, e.g. small box 15x15x15 cm, 0.60 each]. How my carrier charges: [YOUR CARRIER RULES, e.g. by size or weight, whichever's higher]. Padding I use: [YOUR PADDING, e.g. 2 cm of bubble wrap all round]. Work out the cheapest box for each single product and for the 10 most likely combinations of two or three items. Count the box cost and the shipping cost together, and leave room for padding. Show it as a table: order, best box, total cost, and a backup box if the first one runs out. Then tell me if adding one new box size would save me money, and which size. Keep it simple enough to print and tape to the wall. ``` ## Step by step 1. List your products with their size and weight 2. List the boxes and mailers you stock with their cost 3.
