Canon IXUS 860 IS(SD870 IS) is 1990 yuan.
You can go to SM. The quality there is absolutely guaranteed. I wonder how much the price there is different from the online reference price. Anyway, the price there is not high, so you can bargain. Don't bid so much, you can reduce the price to at least three or four hundred below the target price. It's best to shop around, and each price is different.
I also bought a camera there in the first half of the year (it was too impulsive when I bought it, and I didn't refer to it everywhere). It was three or four hundred lower than the marked price, but it was still expensive, so I estimated the price when I went to buy it and visited several stores.
I hope you can buy it cheaper, and you must bargain hard! good luck
