Pennyful is a very nice website, its motive is to provide cashback from their commission received from sale. There are all online website available from where you can earn cashback while shopping. You just need to do is that only just click on the link and you will transfered to that particular page shop and get tracked cashback on pennyful. I alsways do shopping with Pennyful because with all discount I am getting extra cashback as well.
The best part of the website is that here you can compare the price of the product, apply coupon and can earn extra cashback also. Means you are getting triple benefit.
Worst part that I feel there are some restrictions regarding apply coupons available on website only neither you will not receive cashback.
Although I am using this website after reading all terms and condition and till now it was a great experience to earn extra cashback on every purchase.
