【實測中伏定執到寶?】標價 £10.99,埋單竟然收 £9.99?拆解 Costco 收銀機謎團

Costco Price Discrepancy Dolce Gusto

去 Costco 掃貨,最怕就是價錢牌睇錯字,埋單大失預算。但小編最近去入貨,卻遇到了一次「反向中伏」—— 標價明明貴過收銀機,最後竟然平咗?

這到底係員工出錯,定係有隱藏減價?今日就同大家分享這個真實經歷,順便教大家點樣用工具精準對數!

真實經歷:買 Dolce Gusto 膠囊的「意外驚喜」

事緣小編去 Costco 補給咖啡,見到 3 盒裝的 Nescafé Dolce Gusto 咖啡膠囊,價錢牌清清楚楚寫住 £10.99(咖啡是 0% VAT)。

作為一個精明消費者,我習慣一邊放落車,一邊打開自家開發的 Costxx 購物助手,順手輸入了 £10.99。心諗,好多人話收銀收多錢。

點知去到收銀機「do」完,一睇張單,盒 Dolce Gusto 竟然只係收咗 £9.99

小編即刻望多兩眼張單,上面完全冇標示任何「£X.00-」的減價字眼。就係實牙實齒地收平了 £1。

點解會發生「標價貴過收銀機」?

在英國 Costco 群組裡,其實不少街坊都遇過類似情況。綜合經驗,這通常有兩個原因:

1. 系統已更新,但員工未換牌

Costco 的價格耐不耐就調整。收銀機系統更新了新價格,但門市員工可能因為人手不足,或者剛好漏了更換該區的實體價錢牌。

2. 系統更新唔切

有時宣傳品列明優惠減價,但可能減價貨物太多,或者日期開始結束不同。種種原因,門市員工未更新收銀機價錢。

如果掉轉:收銀機貴過標價牌點算?

今次小編是「執到寶」,但如果情況相反 — 價錢牌平,但收銀機收貴了呢?

根據英國的零售慣例(雖然不是法定權利),如果您在結帳後發現系統收多咗,您可以拿著收據和貨品去 Customer Returns (客戶服務部)

有咗 Costxx 購物助手,對數不再靠估

經過今次經歷,我更加覺得邊買邊記錄的重要性。

如果您有用 Costxx 購物助手

  1. 在埋單前,您的 App 已經計算了一個預計總額。
  2. 當收銀員報出最終銀碼時,您可以即時對比。
  3. 如果平咗,恭喜您,有驚喜!
  4. 如果貴咗,您可以即刻在收據上找出哪一項有出入,當場向職員查詢,不用回到家才「揼心口」。

總結

Costco 的價格系統有時的確會有「時間差」,下次遇到標價牌和收銀機不一致,不用太驚訝。最緊要自己心裡有數!

[Scam or Steal?] Displayed £10.99, Charged £9.99 at the Till? Unraveling the Costco Till Mystery

Costco Price Discrepancy Dolce Gusto

When shopping at Costco, the biggest fear is misreading the price tag and going way over budget at the checkout. However, during a recent grocery run, our editor encountered a "reverse scam" — the displayed price was clearly higher than the till price. It actually ended up being cheaper?

Was it an employee error, or a hidden discount? Today, we'll share this real-life experience and teach you how to use a tool to check your total accurately!

Real Experience: An "Unexpected Surprise" Buying Dolce Gusto Pods

It started when I went to Costco to stock up on coffee. I saw a 3-pack of Nescafé Dolce Gusto coffee pods with a price tag clearly stating £10.99 (coffee is 0% VAT).

As a smart consumer, I have a habit of opening our self-developed Costxx Shopping Helper while putting items in the trolley, so I immediately entered £10.99. I was thinking, a lot of people mention the till overcharging.

Who knew that after scanning at the till and checking the receipt, the Dolce Gusto was only charged at £9.99!

I quickly double-checked the receipt, and there were absolutely no "£X.00-" discount indicators. It was just genuinely £1 cheaper.

Why Does "Displayed Price Higher Than Till Price" Happen?

In UK Costco community groups, quite a few shoppers have encountered similar situations. Based on collective experience, there are usually two reasons:

1. System Updated, but Tags Not Changed

Costco's prices are adjusted from time to time. The till system might have updated with the new price, but store staff, perhaps due to being short-staffed, might have missed changing the physical price tag in that section.

2. System Updates Lagging Behind

Sometimes promotional materials state a discount, but there might be too many discounted items, or the start and end dates vary. For various reasons, store staff haven't updated the till prices in time.

What if it's the other way around: The Till is More Expensive than the Tag?

This time I "hit the jackpot," but what if the situation is reversed — the price tag is cheaper, but the till charges you more?

According to UK retail conventions (though not a statutory right), if you find the system overcharged you after checkout, you can take your receipt and the item to Customer Returns.

With Costxx Shopping Helper, No More Guessing at Checkout

After this experience, I feel even more strongly about the importance of tracking prices while shopping.

If you are using the Costxx Shopping Helper:

  1. Before heading to the till, your App has already calculated an estimated total.
  2. When the cashier gives you the final total, you can instantly compare it.
  3. If it's cheaper, congratulations, you've got a surprise!
  4. If it's more expensive, you can immediately check the receipt to find the discrepancy and ask the staff on the spot, instead of kicking yourself only after getting home.

Conclusion

Costco's pricing system does occasionally have a "time lag." Don't be too surprised the next time you encounter an inconsistency between the price tag and the till. The most important thing is to know what you should be paying!

If you've also encountered similar "hidden discounts" or pricing errors at Costco, feel free to use our Costxx Stock Tracker to report them so more group members can benefit!
