We currently support over 80 merchants that you can browse through our extension, including very popular merchants such as Lazada, Amazon, Redmart, Shopee, Agoda, Zalora, Expedia, Deliveroo and many others! We are working hard to provide more promo codes on more sites in the near future!
However, in the off-chance that our extension is not popping up on merchants that we do support, please do let us know at the following email: support@rate.com.sg. Your invaluable feedback would be very much appreciated from everyone here at the RateX team!
