If you join Boots Parenting Club (via the link) you get a £5 off voucher when you spend £20 online.
If you choose 3 x £10 gifts in the Mix n Match Christmas gift area, it knocks off £10 automatically. So when you add the £5 off voucher you are getting 3 £10 gifts for only £15, or £5 each.
Delivery is free to store or £2.90 in the UK.
