Why so few copies?

Why so few copies of the translated volumes available?

I'm asking this as a French-speaking reader.  We see select titles released, since not everything gets translated. But what's most disappointing is that, even among these translations, why are there so few copies for sale?

I don't have exact figures to compare, but i can clearly see there's demand for titles like Eve of Ruin, Shadow of the Dragon Queen, or Keys From the Golden Vault, which sell out completely in stores within a few weeks and create a disproportionate speculative bubble for those unlucky enough to have missed the initial sales. About $28-$45 for a used copy of Shadow of the Dragon Queen in English, compared to $120-$175 in French.

Is this a lack of understanding of this growing market in Europe, with too few copies ordered? Is it the fault of third-party resellers?

I can only assume it has to do with the perceived market.  They don't want to sit on a stockpile of extra books so they plan to sell out.

There may also be some behind-the-scenes things going on with the printers.  Don't know about Europe but that's been hitting the US lately.

If you build it, they will come.
