[keepa] Amazon prices move quite a bit. Let's track prices
Roughly speaking
- Amazon Time Sale is full of boulders and I can't find it anymore.
- Some products suddenly appear on sale at bargain prices. Amazon is dynamic pricing.
- Buy the product you're aiming for when it's cheap. Buy things like stocks.
Amazon Time Sale with Boulders and Stones
On July 24th to July 26th, the first Amazon time sale in a while was held. Recently, it has been held every month, but due to the impact of COVID-19, it has not been held for about three months.
However, Amazon sales are all mixed in recent years, and it's hard to know which products to buy to buy.
Chinese products are in particular becoming more and more popular, and electric Bluetooth earphones tend to line up untidy.
Currently, the expansion into Amazon is becoming a boom in China, and young people are concentrated in cities to launch a new venture, and it is common for them to mass-produce products with blueprints leaked from major manufacturers' OEM manufacturing plants, and have them write reviews around the cherry blossoms.
If you work hard and continue researching, you sometimes find and buy products that are very good value, but it's an extremely difficult task.
It's doubtful that searching for products during the time sale may actually be a great deal. It often induces impulse buying, and ends up "this is enough" without buying the product you really want, and is unable to achieve satisfaction.
It's important to specify the product in advance and buy dips (to buy at the right time when it's cheaper), but is there any way to make it happen?
In fact, keepa has the perfect Chrome extension. But first let's explain how Amazon pricing works. In fact, prices on Amazon products vary considerably.
Amazon prices change every day
Amazon uses a system called dynamic pricing.
This means that the price of a product is dynamically changed based on product inventory, season, time of day, and user attributes.
This is a technique that was mainly used on travel and airline ticket sites, and explicit price discrimination has also become an issue on Expedia.
Amazon is also a profitable company that introduces dynamic pricing. Product prices vary depending on stock and sales period.
Models of PC peripherals such as audio products, HDDs, and SSDs are frequently revamped, and prices fluctuate rapidly. Let's actually take a look at it on keepa.
Buy things like stocks
Keepa is an Amazon browser extension that enables product price tracking, and when searching for products on Amazon, it also displays additional price fluctuation graphs.
For example, the product price page for Sony's noise canceling headphones displays a price graph as shown below. Prices are fluctuating quite a bit.
Price fluctuations over the past year are the lowest price at 29,115 yen and the highest price at 38,880 yen. It's quite different.
You can also set up notifications such as tracking settings for each product and sending an email if the price falls below a certain price.
Let's monitor products that say "I want to buy them, but I think it's a little expensive right now."
