KOOPON!!! Discounts, discounts and more discounts!!!
Noticed this machine at Tampines One!!!
Registration is easy: just SMS <koopon XXX> to 81816664. Replace XXX with your own unique code and you shall receive a confirmation message a few seconds later. Otherwise, you can register yourself at their website.
Once registration is done, you can print out coupons from the machine. I got myself “Free Medium Upsize” with any Carl’s Jr combo meal (T&C applies)!! ^^
