Hadn't checked my Boots app for a while, and just noticed these. 30 extra Boots advantage points, just for selecting one of these drinks with your £1 meal deal.
Funnily enough, these are the 2 drinks I've been alternating between with my Boots lunches, so it may be purely relating to whichever drinks you would normally choose, or Boots wanting to promote these 2, and its co-incidence they've been my choice lately.
If you don't have this offer on your account, try getting one or other of these options for a couple of times, and see if it appears?
It's points for doing nothing, really :)
* deal is stated as running from 03/08/16- 30/08/16
so, if it isn't on yours, try having one or other of these for a couple of weeks, see if it appears? Got to be worth a try. They are really nice drinks too :)
