• Compare prices: Use price-per-serving for accurate comparison; factor in shipping.
• Check reviews: Read independent reviews on shipping speed, customer service, product freshness.
• Review policies: Ensure clear return/refund policy, secure payment, and data protection.
• Consider subscriptions: Auto-ship often yields 5–15% savings; confirm easy cancellation.

Buying in bulk from trusted online retailers can save 20–40% versus brick-and-mortar stores. Always consult a healthcare provider before starting new supplements.
