Our kefir is freshly made to order and shipped refrigerated.
The remaining shelf life upon arrival may vary slightly depending on delivery time — usually about one day less than the expiry date .
During weekends, holidays, HCT/blackcat peak delivery seasons, or if there are delays in receiving the package, the remaining days may be shortened by an additional 2–3 days, which is normal.

Current refrigerated shelf life:
🐄 Original Milk Kefir – 21 days
🍓 Fruit Milk Kefir – 14 days
🌱 Soy Milk Kefir – 14 days
💧 Water Kefir – 28 days

We recommend storing it in the refrigerator as soon as you receive it and enjoying it while it’s fresh for the best flavor.

Since our products are fresh dairy (yogurt), they are not eligible for the 7-day return policy under Taiwan’s Consumer Protection Act.

• If the product is defective, incorrect, or damaged during delivery → Please contact our customer service (line official @642sgfta) within 72 hours with photos. We will send driver to pick up damaged goods, cover the return shipping cost and arrange a refund or replacement.
• If the return is due to customer-related reasons (e.g., incorrect address, recipient not available, uncollected package) → The refund will be processed after deducting the necessary costs (such as shipping fees and spoiled products caused by delay).

Thank you for your understanding.

Delivery Date:
For customer convenience, our website allows you to select your preferred delivery date.

Delivery Time:
Only Yamato (Black Cat) offers time-slot delivery, with two options: before 1:00 PM or 2:00–6:00 PM. Please note that exact delivery times cannot be guaranteed, as the final schedule depends on the courier’s route planning.

In most cases, over 90% of packages are delivered on time. However, around 10% may be delayed due to special circumstances such as high shipping volume during holidays, incorrect recipient address/phone number, recipient not at home, or unanswered calls.

👉 If you have very limited availability to receive packages, we recommend using store pickup service or purchasing directly from one of our partner shops to avoid failed delivery and return issues.

If no one is available to receive the package, the courier will call the phone number provided in your order to arrange a new delivery attempt. If delivery fails more than three times, the package will be returned. In the event of a return, we will deduct the necessary costs (e.g., shipping fees and any spoiled products due to delays) before issuing a refund. Thank you for your understanding.

After the package is shipped, the system will send you an email with your logistics tracking number.

Open the order delivery progress query page on our official website, enter the logistics order number and your email address, and you can track the package.

For customers who use HCT, you can directly join the official line to get more accurate package information.

Basically, if you place the order before 12pm, the package will be sent out on the same day. Black cat generally delivers the next day (except Sunday). Express delivery (Pickupp) will deliver to you on the same day (Taipei City only)

If your profucts are out of stock or it is a pre order product, generally it will be delayed in 1 day or 2. We will email you about the delay.

Yes, that’s possible. Among all convenience stores, only 7-ELEVEN partnered with Yamato Transport (Black Cat) offers refrigerated pickup service.

When placing your order, please select “Yamato Low-Temperature Express to Store – 7-ELEVEN Refrigerated Pickup”, and include the store name and address of your chosen 7-ELEVEN in the order notes at checkout.

Please note that Yamato Transport is a paid service:
Orders below $1300: shipping fee $160
Orders above $1300: shipping fee $80

Once the package arrives at the store, you will receive an SMS notification, and you can then pick it up.

Additionally, 7-ELEVEN may charge an extra “store transfer handling fee.” This fee is currently waived during the promotional period. The end date of the promotion and the exact fee amount will be subject to Yamato Transport’s official announcements.

Please also note that the store delivery service is an arrangement between Yamato Transport and the recipient. If the package is not picked up within the required time frame (within 4 days) and is returned, we will not provide a second reshipment.

Yes, you can do it with black cat, convince store and local pickup at our store. Unfortunately, express delivery (pickupp) in Taipei city doesn’t provide cash on delivery service. 

Please confirm the total amount on the checkout page after applying any discount codes or points. In many cases, the issue occurs because after using a discount, the final amount no longer meets the free shipping threshold.

Currently, orders over $999 qualify for free shipping via HCT Logistics. Orders over $1300 qualify for free shipping via Black Cat Delivery Service or 7-11 refrigerated pickup. For more details about shipping fees, please refer to the shipping methods page
