Just had a look through new offers and there are 3 offers that you may like to stack if you have them as I know can be different from account to account.
I have, 50 points when you buy 2 boots essential products wipes, toner etc these are on offer 3 for £3 at the minute.
Then 100 points when you spend £5 or more on facial skincare. Buying 2 lots of the 3 for £3 taking you to £6 will qualify for this.
Then double points on next transaction will give you 248 points (£2.48 back).
So 6 essentials products (toner and cleanser are normally £1.50 each) for £3.52 basically.
If for any reason these don't go on together I just ring the customer line for advantage card which is found in the help and contact part of the menu in app explain and they put them on manually. As none state can't be used in conjunction with other offers I can't see a problem but with all the previous app issues you never know.
There are exclusions for the 100 points like no7 that's why I used the essentials range as the best example for this.
Double points only has exclusion of can't be used in conjunction with nationwide store points events.
These can only be claimed in store not online.
This range may not be for everyone but hopefully it will help someone.
