- MySweetSmile is promoting a website-only Prime Day sale that stacks 40% off with multi-buy offers, a free £24.99 Precision Whitening Pen on orders over £30, and free next-day delivery.
- A featured basket of three whitening strips and two powders drops from £174.94 to £53.97 under the buy-three-get-two-free deal, bringing the per-item cost to about £9.
- Amazon lists MySweetSmile Tooth Whitening Powder and Strips at £17.99 each during Prime Big Deal Days, undercut by the brand’s direct multi-buy bundles.
- Competing BetterWhite Professional Teeth Whitening Strips on Amazon start at £7.98 for a 14-pack, with larger packs reduced to £10.18 (28) and £13.39 (42).
- Customer feedback is divided, with many reporting noticeable whitening and little sensitivity and others saying the strips had no effect or left residue; MySweetSmile points to strong Trustpilot ratings and recent IndyBest awards.
