What the numbers say
25.0% off the first order ($28.46), then 25.0% off every renewal ($28.46), shipped free. The first order keeps $3.50 and each renewal $3.50. A one-time buyer at full price, paying $8.74 for shipping, keeps $20.30.
If 70.0% of subscribers take each next order, a subscriber earns $11.51 over twelve orders, and never passes the one-time buyer in that time. Retention decides the offer: the table shows three rates.
Free shipping is part of the offer's cost here: every subscription order pays its $8.74 label.

The cost structure, and where it comes from
| Price | $37.95, a bottle of supplements. Nature's Sunshine homepage, read September 23, 2026 |
|---|---|
| Unit cost | $10.47. From the reported gross margin: “Gross margin in 2025 increased to 72.4% compared to 71.5% in 2024.” Nature's Sunshine, fourth quarter and full year 2025 results, read September 23, 2026 |
| Pick and pack | $3.20 per order and $0.48 for each extra item. Fulfill.com, 3PL pricing benchmarks (The Fulfillment Advisor 2025 survey of 600+ warehouses), read September 23, 2026 |
| Shipping label | USPS Ground Advantage, commercial, Zone 5, by weight rounded up to the pound: 1 lb $8.74 · 2 lb $9.95 · 3 lb $11.57 · 4 lb $12.84 · 5 lb $13.48. Packed weight is an assumption: 0.5 lb per unit. USPS Notice 123, USPS Ground Advantage Commercial, Zone 5 (effective July 12, 2026), read September 23, 2026 |
| Card fees | 2.9% + $0.30 per order, a common online card rate. Shopify doesn't publish one rate: it depends on your plan and the card. An assumption. |
| Refund reserve | 5%, Offer Suite's default assumption for consumables. NRF's all-category figure for online sales is 19.3%, but consumables are rarely returned; use your own rate. |
| Gift | a travel-size bottle: unit cost $5.24, retail $15.00. A half-size bottle, costed at half the full bottle's unit cost. |
The offer document an agent would write
This is the offer as a document, the way an agent writes it for Offer Suite's API. It validates against the offer schema as it stands. Ids are placeholders; the discount is stated the way the offer states it, and Offer Suite checks with a real cart that checkout charges exactly the prices above.
