I've had two variants the following mail in my inbox, each with a code to get 50 bonus points: -
"Stock up online for Christmas. Watch your inbox for our emails, each with at least 50 free bonus points. Collect all 510 and you'll have enough for three boxes of capsules or a stylish coffee tray. Happy Christmas! "
As it says, they're giving enough bonus points for three boxes of capsules.
I can only assume this email has gone to all reistered accounts?
Keep an eye out and search through your inbox!!
