Clearance is where items being withdrawn from the regular catalogue are moved to. This is not second-hand stock – it is simply the end of the road for these particular lines: closed editions, repackaged series and odd items that will not be listed again.
The section is divided by type of model into four subsections, so you can go through only the part that interests you. What sits in them changes irregularly, in step with changes across the whole catalogue, which is why it reads less like a range and more like a shelf.
Clearance is worth browsing when you have no single target and are willing to be talked into something. Builders with longer experience often turn up older kits that are no longer produced in the same form, or detail sets aimed at a previous generation of a model. If you do not know a kit well, check how it is broken down and what the box contains before committing: older moulds generally mean more work on fit and on the parting line than a recent tool does.
An older kit often needs the bench topped up, because what the box once contained no longer meets what you would expect of it. Check that you have suitable model paints, decent tools for cleaning parts up, and filler for the seams, because an older tool will give you more of them. Decal sheets of a certain age are worth testing on a scrap before they go onto the model.
If clearance does not hold what you came for, look at new releases or work through the whole branch of plastic model kits, where everything is sorted by subject and scale.
