Tips on shopping for computer/digital products.
1. Always get the quotations from at least 3 shops. Some shops might give a very high quotation seeing a foreigner. For most of the products, you can find them in more than one shops, so check the price as much as you can. Why do you have to pay more only because you are a foreigner?
2. Low end products, like flash cards, low end PC components, could be less expensive than in other countries. But high end stuffs like high end CPUs, display cards, monitors, are probably a lot more expensive than in US, Hong Kong, Japan. Remember to check the prices on websites like newegg before going!
