The button to add points while shopping does NOT work in Chrome. I've tried to apply/use the extension as listed by your site's instructions and it doesn't work at all. Hundreds of pounds spent and not a single point for most of my shopping done. Any and all messages I try to send via Facebook do not go through ever since I threatened legal action based on my personal information being handed out to third parties without my consent along side completing promotional offers after reading every detail in the fine print and getting 0 points. All in all, false advertising, illegal sending/selling of personal information and fraud. User's recommendation: Avoid like the plague.
