Advantages of self-operated convenience stores: do it yourself, decide what to sell, what to open and what to price. Once there are variables, you can change careers or transfer schools. Disadvantages: it is difficult to find a good supplier, and the purchase is unstable, even if the purchase cost is relatively high. Even if the authenticity and purchase price of the goods are found, it is not easy to control. The inventory is relatively large, and there will be losses of unsold goods after half a year. Fresh and fast food products cannot be operated. That's about it, for reference only. I wish you all success in opening a shop.
