Browse the catalogue and some listings show a price and an add-to-cart button, while others show neither. That difference is deliberate and it is enforced by the server, not by hiding a button.
Showing a price is a claim
A displayed price says: this is available, to you, now, at this figure. Where that is not true, the honest thing is to show no price rather than a price that will not be honoured.
So price and checkout are tied to a single condition — the listing has been approved for online sale, its supporting documentation is current, and stock exists. Anything else and the commercial furniture comes off the page.
This is checked when the page renders, when an item is added to a cart, and again when an order is created. A price cannot be brought back by editing the page in a browser, because the page is not what the decision is made from.
The states a listing can be in
Approved for online sale. Documented, reviewed, in date. Price shown, orderable.
Under compliance review. Being assessed, or its documentation has lapsed and is being renewed. No price. This is a queue position, not a verdict.
Enquiry only. May be supplied, but not through an anonymous checkout — because the buyer's eligibility, the destination, or the paperwork has to be settled first. No price; there is a route to ask.
Restricted. Cannot be supplied through this site in the way an ordinary customer would order it. Listed so that people searching for it get an accurate answer rather than silence.
Trade only. Visible to verified trade accounts and to nobody else. If you have not been through that verification you will not see the listing at all, and a direct link returns a not-found page rather than a teaser.
Coming soon and discontinued are what they sound like: one has not been listed for sale yet, the other no longer is.
Why a listing exists at all if it cannot be bought
Because a catalogue that silently omits everything it cannot sell tells you nothing about a supplier's range, and because an accurate "not through this channel" is more useful than an empty search result. What such a listing must never do is imply it can be bought.
What to do about it
Use the enquiry route on the listing. What helps most in a first message is the material, the intended setting, the destination country and the quantity — that is usually enough to say whether it can be supplied and what documentation is needed. Contact us directly if there is no route on the page.
If a listing is under review, asking does not advance it, and neither does asking again. Reviews finish when the documentation is complete.
Why this is worth something to you
A store that shows a price for everything has told you nothing about which of those things it can actually supply lawfully. Here, a price means a documented, reviewed and currently valid position — and the listings with no price are the reason to believe the ones that have one.
