common or not
直接回答，简单介绍情况。
yes. there is a huge number of street markets in china，especially in small towns
it starts quite early，probably around 6 oclock

why you buy things there
思路开阔点，截取两点讲就行（中间注意逻辑连接词和冗词）
i guess people often buy stuff there mainly because they are more economic than things sold in the malls，you know，especially when you purchase a lot
another reason relys on that variety stuff sold there，from local delicacy to some daily necessities.
如果还有理由，补刀一句也行
anyway，they can be found anywhere，and i often go to the street markets with my friends on weekends。

do you prefer buy things from street market or shopping malls
这种问题可以单边倒，可以分情况讨论

more economic／afforded（costly）
