Landed cost: adding shipping to a box price
Webb Peptides ·
The short answer
Shipping is $90.00 for the first 4 boxes in an order and $15.00 for each further block of up to 4. Spread over the boxes, that is $90.00 on a single box but $22.50 a box once 4 are in the cart. Add that share to the box price before working out a price per mg.
How the charge is built
Webb’s checkout charges shipping by the block, not by the box. The first block covers up to 4 boxes and costs $90.00. Every further block of up to 4 boxes adds $15.00. Boxes are counted across the whole order, so a box of one compound and a box of another fill the same block. The charge is worked out once for the order and shown at checkout, next to the box prices, before you pay.
Shipping = $90.00 + $15.00 × (blocks − 1), where blocks = boxes ÷ 4, rounded up
What shipping adds to each box
Split the order’s shipping charge evenly across its boxes to find the share each box carries. The table shows it for orders of 1 to 12 boxes. The share falls quickly while an order fills its first block. Each time a new block begins, the extra $15.00 is spread over the whole order, so whether the share goes up or down depends on how that charge compares with what each box was already carrying.
| Boxes in the order | Blocks | Shipping for the order | Shipping per box |
|---|---|---|---|
| 1 | 1 | $90.00 | $90.00 |
| 2 | 1 | $90.00 | $45.00 |
| 3 | 1 | $90.00 | $30.00 |
| 4 | 1 | $90.00 | $22.50 |
| 5 | 2 | $105.00 | $21.00 |
| 6 | 2 | $105.00 | $17.50 |
| 7 | 2 | $105.00 | $15.00 |
| 8 | 2 | $105.00 | $13.13 |
| 9 | 3 | $120.00 | $13.33 |
| 10 | 3 | $120.00 | $12.00 |
| 11 | 3 | $120.00 | $10.91 |
| 12 | 3 | $120.00 | $10.00 |
Two things stand out. The biggest drop comes from the first few boxes: going from one box to 4 cuts the share from $90.00 to $22.50. After that the steps are small: at box 5 the share falls from $22.50 to $21.00, and at box 9 the share rises from $13.13 to $13.33, because each later block costs much less than the first.
Landed cost of one listing
Take BPC-157 10 mg at $65.00 a box, holding 100 mg. Its landed cost, the box price plus its share of shipping, depends on how many boxes travel together:
- 1 box: $155.00 a box, or $1.55 per mg including shipping (against $0.65 for the box alone).
- 4 boxes: $87.50 a box, or $0.88 per mg including shipping (against $0.65 for the box alone).
- 5 boxes: $86.00 a box, or $0.86 per mg including shipping (against $0.65 for the box alone).
- 8 boxes: $78.13 a box, or $0.78 per mg including shipping (against $0.65 for the box alone).
The per-mg figure printed on each product page is the box price alone, so it can be compared between listings without knowing the size of anyone’s order. The landed figure is the one to use when you are deciding how many boxes to put in one order.
Paying the total
The order total that the order page shows already includes shipping. It is paid in USDT on the Tron network, where one USDT counts as one US dollar, or in bitcoin worth that total when you pay. There is no separate shipping payment and nothing is collected on delivery. Without payment an order lapses after 72 hours, and its boxes stop counting towards any block.
Before you check out
- Count boxes across the whole cart: every listing fills the same blocks.
- Check where the next block starts; one box past it adds $15.00.
- Use the landed cost per mg to compare order sizes, and the product page’s per-mg figure to compare listings.
- The note on price per milligram explains the per-mg arithmetic itself.
The charges on this page are read from the checkout settings each time it loads, so they match what checkout will show for the same number of boxes.
