There is a gap in the counter prices of electronic products in various places. I suggest going to Zhongguancun to check the quotation online. In contrast, the quotation there is relatively reasonable and accurate.

I have also bought electronic products such as cameras by stages, and it feels quite cost-effective. Of course, if you eat a lot, don't think about it. Do you pay by credit card? It's best to see if there are any promotional activities on related websites. I use China Merchants Bank's credit card, and there are often promotions on China Merchants Bank's website. The price of promotional products is sometimes lower than the normal quotation, so it is very cost-effective to buy them in installments.
