Kakobuy shows one price. You pay another.

GRAILS Companion puts the total you actually pay, the QC photos and the seller's record onto the listing you are already reading.

The same hoodie, before and after the shipping Kakobuy works out only once you have paid for the item.

The checks you were doing by hand

Worked out from the listing and the GRAILS catalogue. None of it is guessed by an AI.

The price you actually pay

Item plus shipping to your country, in your own currency, from the real parcel weight. Kakobuy quotes shipping after you have paid for the item, so this is the number it never puts in front of you.

QC photos, on the listing

The batches real buyers received, on the page you are already reading. No second tab, no pasting the link into a QC finder to see whether this one comes out right.

Seller trust

If the seller is in the GRAILS set you get a score and the reasons behind it. If they are not, it says so plainly instead of inventing a rating.

Every agent, one click

The same item on the other agents, so you can compare the shipping before you commit to one.

Weigh the whole haul

One tap turns your cart, or a pasted haul, into a single parcel with a single price. Each item is weighed from its own QC batch where there is one.

On the seller's Yupoo too

Open any album on a seller's Yupoo and one card goes under the header: the catalogue price, how many QC photos exist, whether the seller is vetted, what people on the GRAILS Discord rated them, and a buy button. Album grids get a small price badge on every album the catalogue knows, so you can read prices without opening each one. Sellers GRAILS has never heard of get nothing added.

A quieter Kakobuy

The popups closed for you, and an optional dark theme for their whole site.

kakobuy.com/item/details
A Kakobuy listing with the login popup covering it, and the same listing with the popup removed
The popup that lands on the listing. GRAILS closes it as it appears, unlocks the scroll and tells you what it removed. A popup that follows your own click is left alone, so logging in still works.
Setup
The three setup cards: welcome, how much experience you have, and what you want turned on
Three cards and you are done. It asks how much buying you have done before, then matches how much it explains as you shop.

Three steps, no account

Step 1 Add it to Chrome

One click from the Chrome Web Store. Nothing to sign up for.

Step 2 Open any Kakobuy link

Your own links, or one from someone's haul. It does not have to be in our catalogue.

Step 3 Read the numbers

Price, shipping, QC photos and seller trust are on the page when it loads.

How it is paid for

The extension is free. It applies the GRAILS referral code on Kakobuy, and GRAILS earns a commission on orders you place while it is on. Your price is exactly the same.

It replaces a referral code already set, including one from a link you clicked earlier. The code goes into Kakobuy's own referral cookie. The links you click are never changed, and nothing is added to the address bar. You can switch this off in the extension options and everything else keeps working.

Questions

Is it really free?

Yes. There is nothing to pay and no account to make. It is funded by the Kakobuy referral commission described above, which costs you nothing.

Which browsers work?

Chrome, and the Chromium browsers that install from the Chrome Web Store: Edge, Brave, Opera and Vivaldi. There is no Safari or Firefox build.

Does it work on other agents?

The on-page numbers are built for Kakobuy, and the seller card also works on sellers' Yupoo albums. For other agents you get one-click links to the same item, so you can compare before you buy.

What leaves my browser?

The item link, so the catalogue can be asked about that item. What it remembers about your browsing stays on your machine, and one button in settings forgets all of it.

What if the seller is not in GRAILS?

It says so. You still get the price with shipping, the QC photos and the agent links. A seller GRAILS has never ordered from does not get a made-up score.

Put it on your next order

It starts working on the first Kakobuy link you open.
