Stacking Tips
Combine multiple discount types in a single transaction. These are the most effective stacking combinations at iHerb.
Loyalty Credit + Promo Code + Flash Sale
iHerb's best stack: a brand flash sale (25-40% off) with an applicable promo code creates a combined upfront discount. The 10% loyalty credit accrues on the already-discounted total, building toward future orders. This three-layer approach on high-turnover supplements (protein, multivitamins, omega-3) delivers maximum per-purchase and ongoing value.
iHerb House Brand + Loyalty Credit
California Gold Nutrition and iHerb's other house brands are NSF or similar quality-certified and typically priced 20-40% below branded equivalents (Jarrow, NOW Foods, Garden of Life). Switching to house brand for high-consumption supplements where brand preference is secondary to quality and price maximizes per-unit savings while earning loyalty credit.
Price Match + Loyalty Credit
iHerb's Best Price Guarantee matched against Amazon Subscribe & Save or Vitacost sale pricing, combined with the 10% loyalty credit on the matched price, creates a compound savings layer not available when purchasing directly from the lower-price competitor.
Bulk Order + Free Shipping Threshold
iHerb's free shipping threshold ($40) is easily cleared by purchasing 2-3 months of supply at once. Bulk ordering eliminates per-shipment friction, captures promo codes on the full order, and reduces relative shipping cost on smaller individual purchases.
Price Match Policy
iHerb's price match guarantee lets you claim a lower price from qualifying competitors — both at the time of purchase and up to 14 days after. Knowing the rules can save you from overpaying on big-ticket items.
Best Price Guarantee
iHerb matches prices from authorized online retailers on identical products. Submit the lower price through iHerb's customer service and they will match it.
Everyday Competitive Pricing
iHerb's everyday pricing is typically below vitamin retailers, Whole Foods, and natural food stores on identical products — the price match guarantee captures edge cases where a specific competitor offers a lower price.
Auto-Applied Loyalty Credit
Even when price-matched to a competitor's lower price, iHerb's 10% loyalty credit applies to the matched total — a benefit not available when purchasing directly from the competitor.
Qualifying Competitors
- Amazon Matched on identical product from authorized seller
- Vitacost Matched on identical products in stock
- Swanson Health Matched on identical supplement products
- Lucky Vitamin Matched on identical in-stock items
Exclusions
- Product must be identical (same brand, formula, size, quantity)
- Competitor must be an authorized retailer
- Marketplace and third-party seller prices excluded
- Flash sale and limited-time prices may be excluded
