Living in Bangkok fo my whole (almost) 28 years, new and big department store is such an ordinary. Luxury, high-street fashion, 2nd handed, teenagers, cheap, low-budget, etc…. you name it. I could see most of it. So I would say, they are slightly different. What they try to sell and get the attention from people it might be the look, theme, decoration or promotion.
Central World, one of the biggest department store in Bangkok did something differently. It has special service for baby. It is a baby room where mom can milk and have some comfort zone for little one. Do u see or think of something? Well, me myself think the store try to dig and serve the need of mom group. Very interesting group to catch because they have their full power and decision with their own money. Also, lot of single mom that have to take care their child by themselve. This might be one of the kind that makrle store stand out and earn more from this target group.
