Due to the change in tastes needs of customers, urban tianguis focus on different merchandise. Produce and other basic staples are still offered, but other items are far more likely to be manufactured items such as electronics, name brand clothing and other wares. Relatively few crafts or agricultural items are offered in most city tianguis. Merchandise mostly concentrate on more modern and manufactured items, such as clothing, purses, beauty products, electronics and hand appliances. Those who sell audio and video CDs, a lucrative business, will often have large loudspeakers playing samples of their wares at very high volume.
