Did you know that most electrics are made in Thailand or the countries around Thailand? Since then their electrics are very cheap. If you are planning to buy laptop or some other parts of computer, Thailand will be your final destination.
There is a big shopping mall for electric stuff called "Pantip" Many electric shops are gathering in there, so it is very convenient to compare price among shops. Moreover there goods are mostly cheaper than other countries, so many local people also visit this shopping mall to buy some new or second handed stuff.
