【行前必備】Costco 搶手貨幾時有？教你睇 Costxx 查貨助手「庫存熱點圖」

去英國 Costco 買嘢，最掃興莫過於專程揸車去到，結果發現心水貨品（例如超搶手的蝦餃、特價點心）已經被人掃清光！為了幫大家節省時間同油錢，Costxx 查貨助手推出了一個非常強大的功能 —— 庫存走勢圖 (Heatmap)。

只要學識睇這個圖表，您就可以透過過往網友的報料數據，摸索出該貨品的「補貨規律」！今日就教大家點樣運用這個功能。

一秒開圖：尋找「走勢」按鈕

當您在查貨助手找到心水貨品後，除了可以見到即時的「好多」、「少少」、「唔見」狀態外，最右邊會有一個藍色的 「走勢」按鈕（帶有折線圖標籤）。

按下去之後，下方就會展開一個名為 「過去 5 日庫存熱點圖 (Heatmap)」 的圖表。

圖表拆解：X 軸與 Y 軸代表咩？

這個熱點圖的設計非常直覺，主要由兩個軸組成：

Y 軸 (垂直)：日期。 顯示過去 5 天的日期（例如從 2 月 14 日到 2 月 19 日），讓您對比這幾天的情況。
X 軸 (水平)：時間 (0-24 小時)。 代表一日內的 24 小時，由凌晨 0 點到晚上 24 點。

紅、黃、綠三色代表咩？

圖表上的每一粒「點」都代表了一次網友的真實報料。顏色的深淺和不同代表了當時的庫存狀態：

🟢 綠色點 (好多)：
代表當時貨源充足，見到連續幾粒綠點代表近期返咗大貨。

🟡 黃色點 (少少)：
代表貨架上只剩小量，可能即將斷貨。這是一個警告信號！

🔴 紅色點 (唔見/斷貨)：
代表當時有網友想買但撲空了，貨架已經清空。

💡 進階技巧：點擊熱點看詳細資訊

如果您想知道更精確的情報，可以直接點擊（或游標懸停）圖表上的任何一粒點。系統會彈出一個小黑框，顯示具體的報料時間和狀態。例如：

「2026/2/19 下午 12:21：唔見」

這代表在 19 號中午時分，該貨品已經售罄。如果您計畫下午才去，見到這個紅色信號，可能就要三思，或者考慮去另一間分店了。

總結：運用數據做個精明買手

透過這個庫存熱點圖，您可以分析出不同分店的分水貨品有冇貨，以免去到得個吉。

這個功能有賴大家的無私分享，下次去 Costco 見到熱門貨品，記得打開 Costxx 查貨助手順手篤幾下報料，建立更強大的互助數據庫！

如果你覺得這個新功能好用，
歡迎請開發者飲杯咖啡支持下！☕

[Essential Guide] When are Costco's Hot Items in Stock? How to Use the Costxx "Stock Heatmap"

When shopping at Costco in the UK, nothing is more disappointing than driving all the way there only to find your favorite items (like the highly sought-after prawn dumplings or discounted dim sum) have been completely wiped out! To help everyone save time and fuel, the Costxx Stock Tracker has introduced a very powerful feature — the Stock Heatmap.

Once you learn how to read this chart, you can figure out the "restock patterns" of these items through past data reported by other users! Today, we'll teach you exactly how to use this feature.

One-Click Access: Find the "Trend" Button

When you find your desired item on the Stock Tracker, besides seeing the real-time "Plenty" (好多), "Few" (少少), or "None" (唔見) statuses, there is a blue "Trend" (走勢) button (with a line chart icon) on the far right.

Once you click it, a chart called the "Past 5 Days Stock Heatmap" will expand below.

Chart Breakdown: What Do the X and Y Axes Represent?

The design of this heatmap is very intuitive, primarily consisting of two axes:

Y-Axis (Vertical): Date. Shows the dates of the past 5 days (e.g., from Feb 14 to Feb 19), allowing you to easily compare the stock situation over recent days.
X-Axis (Horizontal): Time (0-24 Hours). Represents the 24 hours in a day, from midnight to 11:59 PM.

What Do the Red, Yellow, and Green Dots Mean?

Every "dot" on the chart represents a real report submitted by a user. The different colors represent the stock status at that specific time:

🟢 Green Dot (Plenty):
Represents abundant stock. Seeing consecutive green dots means a large batch has recently arrived.

🟡 Yellow Dot (Few):
Represents only a small amount left on the shelves, indicating it might go out of stock soon. This is a warning signal!

🔴 Red Dot (None/Out of Stock):
Represents that a user tried to buy it but found the shelf completely empty.

💡 Pro Tip: Click on a Dot for Detailed Info

If you want more precise intelligence, you can directly click (or hover over) any dot on the chart. The system will pop up a small black box showing the exact report time and status. For example:

"2026/2/19 12:21 PM: None (唔見)"

This means by noon on the 19th, the item was already sold out. If you were planning to go in the afternoon and see this red signal, you might want to reconsider or check the stock at another branch.

Conclusion: Use Data to be a Smart Shopper

Through this stock heatmap, you can analyze whether your favorite items are in stock at different branches, helping you avoid a wasted trip.

This feature relies on everyone's selfless sharing. Next time you see a popular item at Costco, remember to open the Costxx Stock Tracker and tap to report it, helping us build a stronger, mutually beneficial database for the community!
