Which network sells photographic equipment?

Do you mean cheap price, large sales volume or good quality?

The cheap one is definitely Taobao, which sells a lot and has fierce competition, but the quality is mixed;

In terms of sales volume, it must be Taobao, with many sellers and buyers.

Determined to return to the store, of course, the price is also very cheap, but it is not the lowest, and the quality is guaranteed.

Dangdang is a monk (who has been selling books before) and I haven't bought it either. It's hard to say.
