Some prices that rose last week came back down unchanged this week. Comparing all 150 items in the TOP 50 rankings across three categories—serums, coffee mixes, and razors—on October 25 and 31, 52 items (35%) had different prices. That is the same number as last week's No. 1 report. In coffee mixes, 25 out of the TOP 50 changed.
The Coupang Weekly Price & Ranking Report is a free report that records the top products sorted by "Coupang Ranking" on Coupang category pages every morning, then summarizes how prices, discounts, rankings, and stockouts moved over the week. Hashscraper publishes it once a week.
This Week at a Glance
To get straight to the point, prices moved the most in coffee mixes again this week, while razors saw both the share of discounted products and the size of discounts increase.
| Category | Products with price changes in TOP 50 | Up / Down | Share of discounted products (10/25 → 10/31) | Out-of-stock products shown in the list (10/25 → 10/31) |
|---|---|---|---|---|
| Essences/Serums/Ampoules | 15 | 7 / 8 | 74.2% → 72.5% | 0 → 1 |
| Coffee Mixes | 25 | 15 / 10 | 56.3% → 53.8% | 0 → 0 |
| Razors/Blades | 12 | 6 / 6 | 70.9% → 74.1% | 0 → 0 |
- Scope: Approximately 850–890 top products sorted by "Coupang Ranking" in each category, recorded every morning for seven days from October 25 to 31
- "Discounted products" are products for which Coupang displayed a discount rate. Products without a listed discount rate are counted separately rather than included as 0% in the average.
- Out-of-stock counts include only products displayed in the list that day. If an out-of-stock product disappears from the list, a lower count does not mean it has returned to sale.
- Options with different volumes or quantities are treated separately even for the same product. If a different option was displayed as the representative option from the first day, it was counted as "changed to a different option of the same product," and prices were not compared.
Coffee Mixes: More Products Rose, With Maxim Concentrated on That Side
Among the TOP 50 coffee mixes, 25 products changed in price, while only 11 remained unchanged. Fifteen products rose and 10 fell. This is the opposite direction from last week (10 up, 14 down). Of the 12 Maxim product rows in the table, 10 increased. However, most were small changes between KRW 20 and KRW 380.
The biggest movers were elsewhere. French Cafe Coffee Mix Stick Mild (ranked 35th) fell by KRW 1,220 (16.9%), while KANU Decaf Americano Stick Mini (23rd) rose by KRW 1,420 (6.0%). The share of discounted products declined from 56.3% to 53.8%, while the average discount rate among discounted products rose slightly from 20.1% to 21.0%. There were fewer discounted products, but the discount per product grew larger. This is the opposite of last week.
Razors/Blades: Both Discounted Products and Discount Depth Increased
For razors/blades, there were six products that rose and six that fell, but discounts increased clearly. The share of discounted products rose from 70.9% to 74.1%, while the average discount rate increased from 33.6% to 36.0%. Razors/blades were the only one of the three categories where both figures increased.
The product with the biggest increase across all three categories this week was also here. Gillette ProShield Yellow Razor Blades, 12-count (15th), rose KRW 7,750 (19.9%), from KRW 38,990 to KRW 46,740. Four of the 10 biggest ranking gainers were electric shavers.
Essences/Serums/Ampoules: Last Week's Price Increase Came Straight Back Down
Among the TOP 50 serums, 27 products had unchanged prices. One notable item was COSRX Advanced The Vitamin C 23 Serum (39th). Last week, it rose KRW 1,790 from KRW 17,670 to KRW 19,460, but this week it fell by the exact same amount, returning to KRW 17,670. You cannot see movements like this by looking at only one week's prices.
In the rankings, Lamucell PDRN Wrinkle Improvement Ampoule stood out. The 3-pack rose from 973rd to 398th, and the 2-pack rose from 702nd to 224th, taking both first and second place among the biggest ranking gainers.

Frequently Asked Questions (FAQ)
Q. How often do Coupang product prices change?
A. This week, 52 out of 150 TOP 50 products (35%) across the three categories changed in price over six days. The number was also 52 last week. In coffee mixes, 25 products—half of the TOP 50—changed.
Q. What is the "ranking" in this report based on?
A. It is the order when a Coupang category page is sorted by "Coupang Ranking." If the same product (with the same option) appears twice on the same day, only the higher ranking is counted.
Q. There were almost no out-of-stock products this week. Does that mean they all came back in stock?
A. That cannot be concluded. This report counts only products displayed in the list that day. Among products shown on both dates in this week's tables, there were zero products newly out of stock or returned to sale in all three categories. If an out-of-stock product disappeared from the list, it is not captured in this number.
Q. Can I get data for the category I sell in?
A. Yes. This report only shows the TOP 50, but the data recorded daily includes product prices, discount rates, ratings, review counts, shipping types, and stockout status for up to rank 1,000 in each category. You can receive a free sample first.
