For those who like to collect different versions of MIKA CDs, a new version of Que ta tête fleurisse toujours was released last month in France (and some parts of Europe?) called the "MOINS CH€R MAINTENANT edition" with a discounted price.

Based on previous experience, it probably is a version with an extra slipcase of the same cover.
