It depends on which city you are in. Generally speaking, if there is a relatively large photographic equipment market in the city, it is definitely the first choice, such as the wedding photography market in Fang Jing Road, Hangzhou. If not, or only a few material stores, then go to the Digital City. In short, go to places where there are many sellers, and never go to places like Gome Suning to buy home appliances. There are few varieties and they are super expensive. The salesman asked questions, but only took money to get the goods.
