BBDBuy Guides | Product Research, QC, Sizing, Costs & Shipping

A product card is good at getting your attention. It is not designed to resolve every question that appears between discovery and international shipping.

This library is organised by decision stage, not by topic popularity. Choose the guide that matches the uncertainty in front of you. You do not need to read everything in order. If you would rather start from the product directory itself, see how to use the BBDBuy Spreadsheet as a shortlist tool.

If You Are Still Learning the Workflow

What Is BBDBuy?

Start here when the agent process itself is unfamiliar. The guide separates product discovery, purchase, warehouse receipt, inspection, parcel building and international shipping so you know which decision belongs to which stage.

Best for: a first agent order or anyone who keeps treating product price and delivered cost as the same thing.

How to Use BBDBuy Spreadsheet

Use this when the problem is not understanding BBDBuy but finding products efficiently. It shows how to write a one-line product brief, enter the narrowest useful category, limit the first shortlist and remove weak options before opening too many tabs.

Best for: broad searches that keep producing too many similar links.

If You Have a Product Page Open

How to Read a Product Listing

A hero image, product title and lowest displayed price do not always describe the same variation. This guide shows how to read option selectors, size/specification data, bundle contents, images and variation-dependent prices in an order that reduces mistakes.

Best for: Taobao-, 1688-, Tmall- or marketplace-style listings with multiple colors, packages, sizes or versions.

How to Compare Product Links

Use this when two links look nearly interchangeable. The method normalizes the variation first, then compares information quality, measurements, visual evidence, price and the one unanswered question that could change the decision.

Best for: choosing between similar sellers or listings without letting the lowest number decide automatically.

Before You Order

This is a stop-check, not another browsing guide. Confirm the current link, exact variation, size or physical scale, product-stage price and any obvious shipping-sensitive issue before payment.

Best for: the final minute before submitting an order.

If Fit Is the Main Risk

How to Choose the Right Size

Use garments and shoes you already own as physical reference points. The guide explains how to compare flat garment measurements, why letter sizes are weak anchors, when body measurements help, and what to do when the seller chart is incomplete.

Best for: T-shirts, hoodies, jackets, pants, shoes and any category where the wrong physical dimensions can make the product unusable.

If the Item Has Reached the Warehouse

How to Check QC Photos

QC is strongest when you separate observation from interpretation. The guide uses category-specific inspection sequences for shoes, clothing, bags, small accessories and electronics while clearly separating what a camera can show from what it cannot prove.

Best for: deciding whether an apparent issue deserves approval, clarification or a closer look.

Warehouse Decision Check

Once the item arrives, the question changes from "Do I like this listing?" to "Does what arrived match what I ordered closely enough to send internationally?" Compare the source listing, order record and warehouse evidence before parcel submission.

Best for: multiple stored items, unclear QC, or orders where one problem item may affect the whole parcel plan.

If Cost Is the Main Question

BBDBuy Cost Planning

Instead of copying a fee table that may become stale, this guide separates product-stage cost, warehouse choices, international parcel cost and destination-stage charges. It also shows how to mark values as known, estimated or unknown.

Best for: searches such as "BBDBuy fees," "BBDBuy cost" or "how much will the whole order cost?"

Shipping Planning

Use this after you understand the products you actually intend to send. Learn how actual weight, volumetric weight, packaging, fragile or route-sensitive items and parcel composition affect the route comparison.

Best for: deciding whether to consolidate, split, keep packaging or compare current shipping options.

Three Reading Paths That Cover Most Orders

Do Not Read More Than the Decision Requires

A guide library should reduce uncertainty, not create homework.

If the product listing clearly answers your size, variation and compatibility questions, move on. If one missing fact is blocking the order, use the guide that helps you identify or verify that fact.

The useful endpoint is not "I read every article."

It is "I know what I still need to know before the next step."
