Cart Saver for iHerb

Check official promo codes against your actual iHerb cart, compare totals, and apply your choice. Open source; no signup.

Keep the cart. Find the saving. Cart Saver checks candidate promo codes against your current iHerb cart and shows the measured difference in the displayed total. Open your cart and click Cart Saver to start checking. Review Total if applied, choose Apply, then Done. No Cart Saver account, AI key or manual code hunting is required. • Automatically updated official-offer candidates for Australia, the United States and Singapore. • Country and currency aware: AUD, USD and SGD in this beta. • Tests up to six codes, then restores your original code when possible. Applying a better result is your choice. • Explains rejected offers and suggests alternatives when exclusions apply. • Optional cashback reminders matched to your cashback account market; cashback is separate from instant savings. • English by default, with a Chinese language switch. • Open source under the MIT license. Cart contents and delivery text are processed locally. They are not uploaded to our coupon feed or an AI model. The extension downloads shared public offer data over HTTPS; hosting providers receive ordinary network metadata. No analytics, affiliate substitution or automatic purchases. See the privacy policy for details. Coupon availability depends on your country, products, account and the merchant's current terms. The beta does not guarantee the lowest price. Review the site's final checkout total before paying. Screenshots show a labelled simulated cart, not a live price offer. Independent project, not affiliated with or endorsed by iHerb, Google or cashback providers.
