I absolutely LOVE Checkout 51 and having received over $100 back from them, I totally vouch for their legitimacy.
This awesome app, which allows you to upload a receipt and earn cash back for eligible purchases has an awesome new offer for new members.
Until September 3rd, new members can earn $5 when they upload their first receipt! Simply register through this link and then upload your receipt – easy peasy!
Cash Back bonus is only applicable when you refer a new Canadian member who signs up and gets credit for uploading their first receipt.
Member must sign up by September 3, 2014, and must upload their receipt within their first 60 days as a member.
