Is the SLR sold by Amazon the Bank of China? Is there a difference between the price and the physical store?

As long as you buy it in China Amazon, it must be licensed. There is no doubt about it. Of course, it may be cheaper to buy it in Amazon abroad, but it is more troublesome.

Compared with a physical store, it depends on what kind of physical store it is. It is definitely much cheaper than big shopping malls, cheaper than Suning Gome, and definitely more expensive than the photographic equipment market, because even if it is licensed, the channels are different.

If you don't know much about it, it is recommended to buy it from B2C websites such as Amazon, Yixun, JD.COM and Newegg. The price is relatively cheap and the quality tour is guaranteed. If someone knows, they can take you to the local photographic equipment market, which will be much cheaper.
