In terms of price, the most expensive one should be the small postal kiosk, followed by the one below silver, and the expensive attitude is poor.
On the cheap side, the red flag price is normal, and Fuxing Supermarket has a discount card to make do. The one next to Houmen North Campus used to be very cheap, but now it has gone up. But generally speaking, online stores in schools I know can often buy some snacks and daily necessities, which can be found by Tesco and Baidu Google. Basically, all goods are much cheaper than physical stores.
As far as everything is concerned, the postal kiosk is the most incomplete. Generally, there are only some instant noodles, bread and milk, paper and pens, cards and the like. Some small supermarkets are just repetitions. I often visit the technology Tesco website, and the variety of things is not bad. I don't ask much. If you are a person who demands a high quality of life, you should go to a large supermarket in the city, where things are of course quite complete, but the price is not as affordable as the Tesco website. And some daily necessities are not sold on their website. You can also give advice to the webmaster, and they will help you get a very cheap price.
