it's safer to buy in a physical store, and you can inspect the goods in person, but the price is a little expensive. It is cheaper to buy online. If you want to go online, if you want to buy it, it is recommended to buy it in JD.COM Mall, and JD.COM Mall sells mainland licensed goods, with guaranteed quality and good after-sales.
I recommend several models, 12 yuan, Canon IXUS115, which is very good for general household use and the performance is ok. Canon IXUS22HS can be considered for the 15, which has very good performance. In 2, you can consider Nikon P3 or Changjiaoni S82.
