Recently decided that me and the kids (3 and 1) will try sambucol, after youngest had 4 illnesses between early August and end September, loads of time off work, dreading more winter bugs! So we're trying it.
found it at Holland and Barrett where if you use their 3 for 2 offer, the subscription discount and a welcome 20% off, you can get 6 bottles for £30. and free delivery. I got 3 adult ones and 3 kids ones.
