Thanks to Rince on MSE for this!!
I emailed Boots customer service about the Christmas Events and was told that they will be having the 1200 points for every £50 spent on boots.com, on the following days:
10th-11th of November
24th 25th of November
The 1200 points for every £50 spent offer does not start until 3pm
1200 points is worth £12.00
Code for 1000(worth £10) extra points on £100 spend might still work KJAH42
Hope this helps
