If you are new to Shopee, use the promo code CATHAYNEW to get $5 off a Cathay Cineplexes movie ticket from seller shopee.lifestyle on Shopee.
Comes down to $3 for a weekday ticket, or $5.50 for a weekend ticket.
$10 off ($20 minimum spend) for new referees through the Shopee app. Referrer receives 500 coins (worth $5) for each successful referral.
The link only shows the Friday-Sunday (weekend) ticket, so it seems the weekday ones are.. sold out? I tried searching for "cathay". Nothing came up.
CATHAYFEST code (listed on the item) takes $1 off the listed price of $10.50, making it $9.50.
Yeah seems expired now, there's also code CATHAY1 which I'm guessing does the same ($1 off).
