Citadium, the large sporting goods superstore that opened in central Paris last November, is on track to reach its sales target of at least FFR300m ($43m) this year, according to Serge Weinberg, CEO of the Pinault-Printemps-Redoute (PPR) group, which owns the store. Sales started to improve during December after a very disappointing launch. However, PPR won't open other Citadium stores until it is certain that the formula will prove profitable.
