Habits that make the difference, including how to judge a site like this one
Four of these are about buying. The fifth is about reading guides, which matters because most of what is written about this subject was written by someone who has not done it.

Read the operator's own pages first
Each figure here was taken from the brand's help text, its API responses or an archived screen, and each one carries the day it was taken. That is not modesty: it is the only honest way to publish a number somebody else controls.
Which means the operator's own pages outrank this one on any question of fact, and should be where you check before you pay. A guide is a map, not the territory.
Its beginner guide in particular is worth twenty minutes before a first order, because it shows the actual screens you will be looking at.
Four habits, in the order they pay off
Save the title, not just the link
Links die and titles survive. A copied Chinese title finds the same goods in a different shop; a dead address finds nothing at all.
Decide the variant before the shop
If the colour is out of stock, the shop question never arises. Doing it the other way round means researching a seller you are about to abandon.
Group by shop, not by mood
Domestic shipping to the warehouse is charged per shop. Two items from one shop usually cost one leg; one item from each of two shops costs two.
Act inside the short clock
The return window runs 120 hours from Stocked in, while storage runs 60 days. People remember the long one and miss the short one.
How to judge a spreadsheet site, this one included
There are a great many sites in this space and most of them are the same six paragraphs in a different colour. Four checks separate the ones that were built from the ones that were generated.
| Check | What a built site looks like | How this site does |
|---|---|---|
| Dated facts | Every figure says where it came from and when. | Every number here carries a capture date, and conflicting official figures are printed side by side rather than silently resolved. |
| Working outbound links | Links to the operator resolve, because somebody tested them. | Every outbound address on this site was requested and answered before it was published. |
| Specific detail | Things only someone who looked would know. | Two inspection photo counts that disagree, two processing windows that disagree, and a warehouse city that two sources put in two places. |
| Stated limits | It says what it does not know. | No founding date, no listing count, no coupon amounts, no league tables, and no claims about whether anything is genuine. |
Run the same four checks on this page while you are here. A guide that cannot survive its own criteria is not worth following.
Other shopping agents, and how to judge a trustworthy one
Other shopping agents exist, a lot of them, and they differ mostly in fee structure, warehouse location, storage window and which platforms they read directly. None of that is settled by a ranking, because the variables that matter are specific to your order: where you live, how heavy the thing is, and how long you want to sit on it.
What you can check before trusting any of them is a short list, and it is the same list whoever the company is.
| Check | What good looks like | How to run it |
|---|---|---|
| Is the operating entity findable | A company name and a registration number you can look up. | Read the terms page. If no legal entity is named anywhere, stop there. |
| Is the fee structure stated | Either a named service fee or an openly stated margin on the rate. | Compare the converted price against a public rate for the same day. |
| Are the storage terms written down | A number of free days, and what happens afterwards. | Find the figure in the help text, not in a marketing banner. |
| Is there a stated remedy when it goes wrong | A return window with a start event, and who pays. | Check whether the window counts from arrival, inspection or purchase. They are not the same day. |
This site is about one of them, because that is the one its links go to, and saying so plainly is more useful than pretending to be neutral. What it will not do is put a number beside a competitor's name. Service quality, dispatch speed and dispute outcomes have no public, reproducible data source behind them, so any league table of them is invented.
If a site ranks ten of these services from best to worst with a score to two decimal places, ask where the data came from. There is no such dataset.
