How does marketing bring value to the goods?

The original reason to write down this article is that I find something in Taobao, the products may in the same shape, and the suppliers may even use the very similar photos, but price A maybe 10 times (or more) of price B. Why and how? I am curious about this situation and then try to find the differences between them.

Case 1 ceramic jars

Case 2 glass bottles

1. Usages
Case 1, they are the ceramic jars, but the cheaper one (A) said it was used for containing tea leaves, while B said it was used for containing the ashes of the dead pets. Their photos are almost the same.

Case 2, they are the glass bottles. The cheaper one(C) is for the hamster to cool itself in summer, while D is for people to cool the Japanese sake.

An ancient story about the chapped cream may tell the same reason. A farmer sold some effective chapped cream to the other farmers to protect their feet in winter since they had to work long time in the farmland. One officer heard that and came to buy the formula from the farmer with a high price, and then the officer dedicated the formula to the King.
At that time, this country was fighting with the neighboring country. With the chapped cream, the soldiers could run quicker and move freely in the cold weather and they finally won the war. The officer was rewarded a fief which was much more valuable than the price he paid to the farmer.

2. Target clients
Jar A’s target is the people loves tea, while B jar’s target is the lover of pets. In common, to the lovers of pets, pets might be the families to them, and they had spent a lot of time together and had many happy memories, thus, the lovers of pets will be more possible to pay high price than the tea lovers.

Comparing to the pets, people may pay more for themselves for the high level experience; it may one of the reasons why glass bottle for sake is more expensive than the one for hamster.

3. Pictures & Packaging
To hunt for the beautiful things is the common desire of human. Even people sells the same product, the one using the nicer photo or packaging could attract people more. Someone told me how he sold neckties. Normally if we thought we are wearing the high-class suits and ties, we may feel confident and easy to leave a nice first impression to others. Thus, his key is to pack the ties with the refined boxes and make them look high-class.

4. Advertising proposal
The proposal should reach the demand of the targets. At the beginning, the Glass bottle B for the dead pets ashes will use the words remind people their memory between them and the pets, gradually, the pet lovers may think their pets deserved an expensive jar.

All above factors will be considered while we are making marketing plans, now you see how marketing brings the value to the goods. But I would say, the high quality and good service are the final key to keep the client stay with us long terms.
