Yes, you're reading the title right: Earn some cash back while shopping online. But that's too good to be true. No it is not. I'm not sure how the business model is, but I'm guessing (even suspecting) that your profile gets combined with other individuals who bought similar stuff and in turn you get targetted advertising.
If you're comfortable with that notion, then proceed with reading this the rest of this post.
The cash back, which others coin "rebates", is through a Mobile App called Shop Back. This is my affiliate link and if you use the link, you and I both get PhP 100 in credits (after you make a verified purchase of PhP 500).
I buy several stuff online through Lazada and have them delivered to my work place. And "Shop Back" has given me back around PhP 600 in rebates. I don't mind the data gathered as it is available to Lazada, and I would have made the purchase through them, regardless.
Shop Back has provided the opportunity to earn back some income made from online purchase. The cash back can be deposited to your bank of choice, or through PayPal.
Also, it is not limited to the online merchant Lazada. It works for Food Panda, Honest Bee and several online platforms.
