First of all, it's true that this is the wrong place to post. Should've been in the Market Place. But to answer your question. Assuming you are from Miri. The nearest one would be a shop in Seria called Asmin. Located at Seria Plaza. But the price there; depending on the salesman of that day, can be quite steep. The range they carry is also limited. If you can move up to Bandar, there are a few that carries original YY. One is a shop called Karisma Sports at the Centrepoint hotel Gadong area. Small shop. They do carry flypowers and victors(limited) too. Not far from Gadong is Kiarong, where the famous Jame Asre Mosque is situated. There's a shop called Spotech. They carry quite a comprehensive range. Shop is situated to the business area (Baiduri bank area) just across the street from the mosque. They are behind at Block D if im not mistaken. Another one is Imperiall sports. One is located at Batu Satu Area, next to a restaurant named Charcoal or around Plaza Athirah area. Another branch is in Citi's Square, around the airport area. Another one shop (can't remember the name) is just next to Gloria Jean's coffee. They do carry ori yonex's too. If you managed to get there, stop by the coffee shop and send my regards to the cure Baristas there. Hope that helps.
Easy. Beside Mubarak and near La Mee restaurant and in front of Ahan Tai Restaurant. Avoid Imperial and Asmin coz they sell both fake and original yonex. They will tell you at the right shelf is ori and at the left is fake (just $50) but you can't be sure if they mix it. Inexperience customers may not be able to tell the fake with the original coz the apperance is the same
