Have you tried Jingit ?

Jingit is great because you earn actual cash (that can be added to your Jingit debit card). Simply download the Jingit app on your smart phone or use the Jingit website.

You can earn money from watching ads, scanning products at Walmart and even for buying those items. It is easy to transfer the money from Jingit to your debit card, and can be used anywhere a credit or debit card is accepted.
