A cake, cause life thinking, so saving money is like this. ...

Passing by a cake shop, a customer asked the boss how much the cake was. The boss said a kilo of cake 10 yuan, and then sent 5 yuan cake, and the customer bought the cake!

This is a very common consumer life scene. For customers who buy cakes, 10 yuan is very cheap to send a catty to 5 yuan! Buy!

Let's analyze it further: the customer bought a cake weighing 10 yuan, and the boss gave it to 5 yuan. In fact, the customer bought a cake weighing 1.5 kg and spent 10 yuan.

Indeed, this is a promotion method. In fact, if this cake is not calculated according to this promotion method, and customers spend 10 yuan to buy 1.5 Jin of cake, then the A Jin of the cake should be 7 yuan.

Then, there are three possible assumptions about the original price of this cake:

Case A: The original price of the cake has not changed since 7 yuan, but the promotion method has changed, that is to say, the cake is actually a catty of 7 yuan, but the merchant has changed the promotion method: the price has been raised to1catty of 0 yuan, and then it will be sent to 5 yuan!

B Situation: The original price of the cake is lower than that of 7 yuan, so we assume that 6 yuan is a kilo.

Case C: The original price of the cake is higher than that of 7 yuan. Let's assume that it is a catty of 8 yuan.

Let's analyze:

One situation is the scene we mentioned at the beginning. The customer thought it was very cheap, and happily spent 10 yuan bought 1.5 kg of cake.

Case B, a kilo of cake was made in 6 yuan, so the customer bought a kilo of cake from 6 yuan and 1.5 kilo of cake from 9 yuan!

Case C, a catty of cake starts from 8 yuan, so the customer buys a catty of cake from 8 yuan, 1.5 catty of cake is 12 yuan!

In the case of BC above, it is obvious that the merchant raised the original price to 10 yuan, and then presented 5 yuan cake to make users feel that the activity was very favorable!

Regardless of whether the original price of the cake is lower than that of 7 yuan and 6 yuan, or higher than that of 7 yuan and 8 yuan, in short, the merchants raise the unit price of the product to 10 yuan, and then give away 0.5 kg, which is a promotional means given after the price increase!

Then let's think about another problem, that is, if the original price of the cake is higher than 10 yuan, such as 12 yuan, then the customer buys 12 yuan, 18 yuan! Obviously, it's too expensive!

Even if the merchants say that the current activity is to reduce the price of 8 yuan and then send it to 5 yuan, and return to the original point 10 yuan, and then send half a catty, then this issue will be withdrawn from the issue of commodity profit!

Only low-priced products can be sent after the price increase, and high-priced products can be sent after the price reduction. Obviously, it is a loss-making business for businesses, and the short-term profit is ok, which is definitely not a good policy in the long run.

Let's go back to the original situation. A. Cake is a short-term preserved product. In the way of promotion, customers 10 yuan can buy a catty and give another 0.5 catty. For customers, it is a good thing that falls from the sky. For merchants, digesting short-term preserved products is the best profit.

I'll call the above situation A cake promotion first, which means that merchants use gifts to attract customers to buy after raising the price of products.

As a merchant, the purpose is simple, to maximize profits as much as possible. There are many kinds of common promotion methods in our market, and the probability method of lottery can't quantify the gains and losses, so what this article wants to talk about is the quantifiable promotion method. I gave some examples of our common promotion methods, mainly the following:

Special price (price reduction), full reduction (cash back, coupon refund), full delivery (coupon delivery, gift delivery, buy one get one free, buy two get one free), discount (one discount, multiple discounts, full discount), special discount (half price for the second piece, plus * * yuan for purchase). ...

In fact, the price increase is a means of promotion, but it will not be disclosed to customers, but we need to judge whether the price increase means is used behind the promotion means we have seen for this product.

There are many other means, so I won't list them here.

My assumptions are divided into two types: case a, no price increase; B situation, raise the price.

Then, according to the above promotion combination, the methods that merchants can use to maximize profits are (incomplete):

Of course, the contents of the form may not be completely believed. It should be noted that the above quantities are variable, so we must consider specific variables to measure the differences behind them. The picture above is just a simple example.

Some people may say, is it so complicated to buy things? In addition, it seems that businesses should not raise prices publicly.

No matter what the actual situation is, as consumers, rational consumption is necessary, regardless of the size of money. People who know how to manage money should know that the most effective way to calculate expenses every day and reduce unnecessary support is to be alert to the trap of business promotion. It is not necessarily a good thing not to buy unnecessary things and occupy the living space at home.

So, for consumers, how to spend more rationally and save money in life?

The principle of making a shopping list is to buy what you need now. If you don't buy a bunch of interesting impulsive consumption that you think is fun, it is a waste of money. At the same time, a bunch of useless items occupy the space at home, which can easily lead your life into chaos.

Knowing the product value behind the activity, do you want to estimate whether this promotion is really a discount or just a promotion method of the merchant? Mental arithmetic is very important.

What's more, if you know how to distinguish the promotion methods of merchants, such as raising the price and then giving it away, it is a very cost-effective thing for merchants, while for consumers, it may be more cost-effective to directly reduce the price, because you don't need to spend extra money on the same product, even the goods given to you by unnecessary merchants.

What you need to think carefully is: ① Put the word "full" before the preferential measures. Do you really need these products? 2 When sending "coupons", if you don't think clearly about when you will spend the next time, be careful!

Finally, I hope * * *
