GreenJinn is an app based service which gives you cash back on a variety of grocery products. The app currently only offers cash back from Sainbury's, Tesco & Waitrose.
The app updates on a regular, more or less weeklybasis, offering a range of different grocery products.
I find this app system offers more discounts off the more main stream products as well as the more 'fancy' products, so there is more chance of getting a saving on something you were actually looking to purchase anyway!
As per many of the other shopping apps, you select the items you want instore, pay the normal price, and then using the app, Once you have purchased the items, open the app, select the items you wish to claim for, scan the barcodes of the products you are claiming for, take a photo of your receipt and upload it. Once the receipt has been verified, GreenJinn will credit the cash back to your account. Once you have reached an account balance of £1.50 you can cash out to your PayPal or bank account.
Cash back amounts will vary by product and is usually between 30p and £1.
