Soft drinks are mostly drunk directly from containers, so the extra storage cost brought by cylindrical containers is offset, because it needs to be weighed by hand. This is not the case with milk. Most people don't drink milk directly from the box.
If the milk container is cylindrical, we need a bigger refrigerator. But even if most people drink milk directly from the box, the principle of cost-effectiveness indicates that they are unlikely to be sold in cylindrical containers. It is true that square containers (no matter what is inside) can save shelf space, but the space saved in the case of milk is obviously more cost-effective than that in the case of soft drinks. Soft drinks in supermarkets are mostly placed on open shelves, which are cheap and usually have no operating costs. However, milk needs to be specially packed in the freezer, which is expensive and has high operating costs. Therefore, the storage space of the freezer is very valuable, which improves the income of square container milk.
Why brand-new used cars are much cheaper than new ones. As long as it is a new car, whether you have never driven it once or for a month, as long as you land, there will generally be a discount of up to 20%. This is the so-called new car "20% off the ground". The new car depreciates the fastest in the first year, and it is the most valuable in about 3 years, so it takes 3-5 years.
Quasi-new cars are cheaper and more cost-effective than new cars. Even if the color is new, it is a used car. As long as it is second-hand and old, the deep-rooted "virgin complex" in the minds of Chinese people will cause trouble, but the cruel fact is that the test driver has taken away the "first time" of the car. Faced with a 20% discount on quasi-new cars, many savvy car owners generally expressed their willingness to give up the same new car and choose a quasi-new car.
Buying a used car saves 10% of the purchase tax. Buying a second-hand car is not only simple, there is no problem of paying vehicle purchase tax, but buying a new car has to pay 10% vehicle purchase tax, and the purchase tax paid when the new car is transferred to a portable car is wasted. In other words, as soon as you buy a new car, it will depreciate by 10%, while buying a used car will naturally save the cost of 10%, because you don't have to pay the purchase tax at all.
Used cars are discounted due to vehicle defects. Almost brand-new used cars are often sold months or even weeks after the owner just bought them. The reason for changing hands is to like the new and hate the old. Even if the running-in period has not passed, there are likely to be various uncertain risk factors such as accidents and scratches. The purchase mainly bears these defects and uncertain risk factors, and the price of natural new cars is much cheaper than that of new cars.
Second-hand car accessories can be used for free, and you can enjoy many configurations that originally required the owner to pay extra when picking up a new car, such as added parts or modified audio, navigation, whole car film and so on. You can enjoy the second-hand car for free, and the owner doesn't have to pay for it himself. In other words, if you choose to buy an almost brand-new second-hand car, you can enjoy the additional configuration of the new car for free just by spending the money on the second-hand car. It is free to enjoy the insurance before the new car is renewed. Although the quasi-new car is much cheaper than the new car, as long as it is within the warranty scope, it can enjoy the same original factory warranty treatment as the new car. If the owner is lucky, he can enjoy the insurance for a short period of time for free before the insurance expires, which saves the cost of buying auto insurance.
Why do restaurants offer free refills? The profit can be calculated like this. Suppose the profit of a drink is 80% of the price. When the customer refills the second drink, the profit becomes 60%, and the third drink is 40%, until the profit of the fifth drink is zero, and the loss begins from the sixth drink. In reality, most customers' refills are controlled below three cups.
So what will this loss of 40% profit bring? If a restaurant offers free refills, customers will think that their consumption cost will be reduced and they will patronize more frequently. However, the refilling customers are rarely alone, and the potential customers brought by this customer will also increase. In the catering service industry, with the increase in the number of customers, the average cost of providing services to customers will decrease. If this lost 40% profit brings extra customers, the profit of the restaurant will increase relatively. Because free refills increase customers' stay time in the store, for potential customers who don't choose a dining place, the probability of choosing will also increase due to the role of herd consumption psychology.
Of course, in order to make ends meet, in addition to refills, the profits of other catering projects must offset this loss. Therefore, the main source of income for restaurants offering refills will not be drinks, and other catering projects will bear the cost of refills, so the overall profit of restaurants will increase.
