Delivery at this size
Whether a pack ships free depends on the order value against our delivery threshold, and this tier's position relative to it is stated below rather than implied.
One pack sits below the free-delivery threshold of £40, so standard delivery by Royal Mail Tracked 48 (2–3 working days) is £3.90 on an order of one. It is shown in full before you pay. Next day by Amazon Shipping is £5.00 if you order by 3pm on a working day.
Storing ten vials
Keep the sealed vials at room temperature until you need them; there is no need to fridge the whole pack. Only the vial you have opened goes in the fridge at 2–8°C. Ten sealed vials keep exactly as one does.
