Proto Flow Shipping: US Costs, Delivery & Tracking
The seller lists free US shipping with its 3- and 6-bottle advertised packages; the linked shipping policy lists 5–8 business days for mainland US delivery and 12–20 business days for Alaska and Hawaii.
Shipping fee by package
The main offer page shows an extra shipping fee on two bottles and free US shipping on the three- and six-bottle bundles. The dedicated shipping policy lists $9.95 or free domestic shipping depending on order size. Final charges and eligibility are determined at checkout.
Dispatch and delivery estimates
The seller shipping policy says dispatch normally occurs within 24–48 hours after order and payment confirmation. Its published mainland US delivery estimate is 5–8 business days; Alaska and Hawaii are listed at 12–20 business days. These are estimates, not delivery promises from this publisher.
Tracking and problems
The seller says buyers receive an email with a tracking ID and shipment link. Check spam folders and the order confirmation if updates do not appear. For address corrections or shipping problems, contact the seller using the link in its shipping policy.
International delivery
The seller also lists destinations outside the United States, but this site is written primarily for US readers. Shipping charges, customs and eligibility can differ by destination and change over time. Verify the actual destination at checkout.
