Customers will be given ‘warning’ during checkouts at the cashier that their items are non exchangeable and non refundable. The cashiers say it according to their management’s instruction: ‘please note that these items are not exchangeable and non refundable’. Some are ‘stamped’ on the receipt (Fig. 1).
I would usually say, ‘yeah, ok’. Why would I even need to bother telling the cashier who is not in a management position about Lemon Law? But I know what Lemon Law is and my rights to replace/exchange a DEFECTIVE GOOD.
So, for all customers, your rights are protected under Consumer Protection (Fair Trading) Act Chapter 52A (https://sso.agc.gov.sg/Act/CPFTA2003), under Part III Additional Consumer Rights in Respect to Non-conforming Goods (i.e., defective goods).
If you got a defective goods, you can get it replaced with the same design, size, or model of the product. In the event that there is no suitable replacement, you can get an exchange (provided that you are agreeable), i.e., to switch the defective item with something of equivalent trait or value. If there is no suitable equivalent value to exchange, you can get a refund!
Some company are more open about their return policy, e.g., Art Friend (Fig. 2).
So, if you encounter an outlet or staff that says your goods are non-exchangeable and non-refundable, THE RULE IS NOT BINDING BECAUSE IT IS SUPERCEDED BY LEMON LAW.
