I still buy myself advent calendars, and now there's an actual one that's supposed to be for me. The Boots Advent Calendar is £30, but has over £65 worth of products, both travel size and full size, inside. Brands include Nails Inc, Soap & Glory and Seventeen.
There is also a deal as part of the package where you earn three times the Advantage Points if you go on to buy the products you've sampled in your calendar. Pretty sweet.
