Just received an email from Klook regarding 2 for the price of 1 for airport transfers advertised on their website if you use promo code 241AIRPORT. Airport transfers include those in Bali, Bangkok, Phuket, Tokyo, Hong Kong etc
2 return Hong Kong Airport Express Tickets reduced from approx RRP of $76 on Octopus card to $26.55 after discount with the voucher code.
May also work for some lucky folks on Skybus tickets, with 1 return Melbourne Tullamarine ticket for only $18.25, the cheapest ever!
If you are a new customer, you may be able to stack with one of the referral links below to make the deal even sweeter.
ALSO, don't forget Shopback cashback of 4%.
Important note: paying by PayPal avoids any hidden foreign transaction fees that have sometimes been charged - see previous Klook deals.
