S3 Sensitivity Science Discount Code and Toothpaste Prices

Is there an S3 Sensitivity Science discount code?

Yes. The code on this page takes 10% off a first order for new customers, and on a subscription it covers the first payment only; it is listed until 31 December 2027. Buying 3 tubes once also has its own 10% code, which brings the pack to £53.99 instead of £59.98.

S3 prices: one-time and Subscribe & Save

• 1 tube: £19.99 once, or £14.99 per delivery on subscription (every 1 to 2.5 months).
• 2 tubes: £39.98 once, or £29.98 per delivery on subscription (every 2 to 5 months).
• 3 tubes: £59.98 once (£53.99 with the pack code), or £39.99 per delivery on subscription (every 3 to 6 months).

A subscription has no minimum number of deliveries, and a delivery can be skipped, moved or cancelled from the account.
