"Portable Wi-Fi" Review
25/03/2022
Amazon often carries out time-limited promotions, such as "Cyber Monday" and "Black Friday". In promotions, we often see items with high discounts such as 70% or 80% discount, "if it's so cheap." "A lot of people can't help being startled. However, in such highly discounted goods, there are also illegal practices such as "raising the price at the beginning of the promotion, although the same price as usual only looks like a large discount rate". Let's see if there has been unreasonable price manipulation and provides a very useful tool, "this is essential if you are no longer shopping at Amazon."
When shopping at Amazon, it is common to accidentally buy at a high price and regret afterwards. In addition, in time promotions such as "Cyber Monday", although it is called a "60% discount on the usual price", it actually increases the corresponding price, and it is only when the goods arrive that they know that the price is not much different from the usual price. and often disappointing.
In this case, you can use the free browser extension "Keepa". This is an extension that shows the changes in product prices over the past year. Because the lowest price and the highest price are clear at a glance, it is possible to accurately judge the purchase time of that item.
Keepa also has a website version, which usually uses an extended version of the browser (which supports Chrome, Firefox, Opera, and Edge browsers) to embed charts directly into Amazon product pages. Let's take a cursory look at how to use it.
After the extension installation is completed, the Keepa chart is automatically displayed on the Amazon product page. This is a convenient place to go back to the past, not the data at the time of installation.
In the initial setup, the object period is based on the status of new products and second-hand products for the past year. By hovering over the chart, you can check the price at a specific date and point in time, reduce the time and display the lowest and highest prices. You can also check the price at the time of sale by clicking on it.
In addition, you can track prices, change status, such as price cuts and inventory restoration, and receive time-limited promotion notifications. Once you start using it, you won't be able to shop on Amazon.
Only the computer version of the browser can install the extension function, so it cannot be imported on phones such as iPhone. However, if you visit the Keepa website on your phone and enter the product code (ASIN) in the search window, a price change chart will be displayed.
Keepa has rich and convenient functions, and there are more and more enthusiasts in Japan, but this is not a panacea. For example, the data for price changes is bound to the product page, and when the URL changes, it is reset, which is the best example.
It is mainly the common situation in the goods sold by overseas operators, if there is a low score in the review of the goods, the page will be temporarily reset, another page will be launched, and the sale will start like a new product. It is said very quickly that it is "selling away" inferior goods.
In this case, Keepa will not inherit the past price changes, which seems to be a brand new product. If the seller insists on a different product and the commodity code (ASIN) is different, it is impossible to take over the past data, and there is no countermeasure for the user.
Indeed, these Keepa countermeasures are only done. Keepa is a well-known tool, so it is natural for operators to consider the implementation of a certain degree of countermeasures after investigating their characteristics.
However, you can also take countermeasures by removing items that Keepa does not have past price information from the object of purchase, or if the number of comments is unusually large compared to the display period, you are more likely to have cherry blossoms. It depends on the solution.
In any case, Amazon's fraud and its countermeasures have always existed, so you need to be cautious when using Keepa.
