I got a similar deal last year from Amazon and have been taking them one a day since January for tree pollen hay fever. I have found them very effective and it worked out way cheaper than i would normally spend on antihistamine. Just checked: i paid £4.49 for them last October (different seller). Edit again: i got a 6 month supply but this deal is for 12 months so indeed a great deal if it suits your needs.
It's not like they go off - they'll still be effective after the use-by date.
i see it's now listed at £5.55 someone expired it but its still listed available so stock up while it lasts
Ok if two or more in a household need.
Sorry just seen that they expire in 6 months
