Boots is currently offering double points, which is worth 8% in points but not only that, you will also qualify for free delivery if you spend over £35.
Also remember that you can go through Quidco to receive 6.5% cashback and if you're total comes to around £50, you can also receive another £5 in points by adding the voucher code at the bottom and i think there's a 1000 points code (worth £10) if you spend over £75, so i'll add that to the post.
Hope this helps and remember this can be used on anything in there online store including valentines gifts :)
In brief, if you spend £75, you'll receive £16 back in boots points and about £4.90 cashback plus free delivery bringing your £75 order down to £54.10 plus free delivery.
Or if you spend £50, you'll receive £9 in points and £3.25 cashback plus free delivery, which will bring your £50 order down to £36.75 with free delivery.
