A receipt used for registration must come from an order that was paid successfully, through a designated channel, within the campaign period (6 November 2026 at 10:00 to 15 November 2026 at 23:59).

The receipt or order image must be sharp, unaltered, and show all of the following:

• The items in the cart
• The Order ID
• The net amount paid (enter the amount including shipping)

Upload a screen capture of the order on which the order number is clearly visible.

One registration covers 1 name and 1 receipt only. You may use several receipts to register, up to 5 receipts per submission, and each receipt or order number must be a new one that has not been used before. A receipt that has already been registered cannot be used again.

No. One receipt may be registered under one name only, identified by its receipt or order number, and the entries it earns follow every eligible item on that receipt. To register under separate names, split the order into separate receipts.

If one capture cannot show every detail, you may upload up to 3 images per receipt.

You may upload up to 5 receipts at a time. Each receipt still registers once, under one name, on the same conditions as before. Press "Add a receipt" to add another.

No. You can register retrospectively up to 17 November 2026 at 23:59, as long as you state the purchase date on the receipt correctly. The system counts earlier receipts automatically, provided the purchase falls between 6 November 2026 at 10:00 and 15 November 2026 at 23:59.

The system updates once the receipt has been reviewed, within 1-2 days. You can come back and check your entry count on the campaign website at any time.

No. Where two submissions carry the same order number, the system counts only the first one that was uploaded correctly.

Enter the net amount you actually paid - that is, the total including shipping and after any coupon discount.

The system treats the name used at registration as authoritative, and it must be your real name as it appears on your national ID card or passport. It cannot be changed after registration is complete. If you find you entered it wrongly, contact the team through LINE Official Account: @antidotes as soon as possible, before registration closes, so the case can be looked at individually.

The name used for registration does not have to match the name on the order or the delivery.

Yes. You can check your entries and your accumulated total yourself on the campaign website (campaign website — URL TBC) you registered with.

Your number of entries is calculated from the entries of every eligible product you bought and registered successfully, over the whole campaign period.

There is no limit on how much you may buy, and you receive entries for every eligible item you actually bought. For example, 1 bottle of Body Perfume EDP 50ml and 1 bottle of Mini Perfume 10 ML EDP earn 5 entries in total.

Each participant may receive at most one prize. If a name that has already won is drawn again, another name is drawn in its place, until a participant who has not yet won this campaign is found.

An order entered in the campaign cannot be changed or refunded under any circumstances. Where an order is cancelled or a payment is incomplete, the Company reserves the right to deduct the related entries from the calculation. Where a change of items leaves the receipt outside the conditions - for example, it no longer contains an eligible product - the Company will consider voiding that receipt’s count.

No. A prize cannot be exchanged for cash or transferred to anyone else under any circumstances, and each winner may receive at most one prize for the duration of the campaign.

The Company has no policy of asking customers to pay outside its designated channels, and no policy of accepting transfers into personal accounts under any circumstances. Where such conduct is found, the Company reserves the right to accept no responsibility for any resulting loss. Please order only through the Song Wat branch, LINE Shopping, and the official Antidotes website.

The Company reserves the right to refuse entry, to this campaign and to any future one, to anyone with a record of fraud or of breaking the rules of any Antidotes campaign.
