The offer entitles you to 10% off the purchase price (excluding postage costs) on the Eligible Item sold by roborock_australia (“the seller”), up to a maximum discount of $500 per transaction. Multiple items may be purchased in five transactions (up to a maximum of 10 items per transaction).
This offer will be available for a long as it is displayed at: https://www.ebay.com.au/itm/363116325016 or while stocks last (“Offer Period”). Once gift cards are exhausted, the offer will no longer be displayed.
All users that successfully redeem this offer will receive a bonus $100 eBay Gift Card. There is a strict limit of 1 gift card per transaction
It seems that the official RoboRock AU website has a similar deal on, but you get a $100 Mastercard Gift Card instead of an eBay one with the same 10% discount.
