I read in another thread recently, (and I can't find it), someone's suggestion that there is a good store/parfumery where top quality and legitimate eau de toilette/parfum is available in Bangkok, (with better pricing say that Kong Powder at Suvarnabhumi). Can anyone enlighten?

Jae Leng's mini department store near the old airport. Drive by the international terminal, domestic terminal, and about 1 kilometer from the cargo terminals (the last one is the TAGS cargo terminal). Legit as in real, but not quite as legit as it's fairly well known that she has built her empire on goods smuggled through without payment of import duties.
