I just recently find this site shopback quite interesting. The idea is that you need to click the link to go to few online sites (e.g. Groupon, Zalora, Courts, etc), and it will give you some cashback vouchers for your purchase, which can be ranged from 1% to 10% or even more for promotion or events.
You can also use this site to find current voucher code or promotion that you will miss out before your purchase. So, it is simple to use, just visit shopback first, search the online merchant you want to go, look for any promo there, and click the link to the merchant website to purchase. For most cases, you will be able to see the cashback under Pending status, which should be redeemable after 1-2 weeks. So far so good although I have not reached minimum amount to redeem yet ($10).
