| Option | Customer pays | Shipping charged | Costs | Margin | Margin % |
| --- | --- | --- | --- | --- | --- |
| 2 units, no gift | $75.90 | $0.00 | $40.21 | $35.69 | 47.0% |

Every figure is computed by the margin engine in Offer Suite's own code, in whole cents, from the costs below.

## What the numbers say

The gift is a travel-size bottle. One unit at $37.95 comes with none, two units with one and three units with two, all at full price and shipped free. The first tier's gift costs $5.72 and the second tier's two gifts $11.44: each gift's unit cost and one more pick.

After its gift the two-unit order keeps $29.97, against $11.69 for one unit, and the three-unit order keeps $47.05 after two gifts. A buyer who steps up from one unit to two adds $18.28 of margin, and from two to three $17.08.

A buyer who was taking two units anyway now costs $5.72 more, and one who was taking three $11.44 more. At the first tier, one step-up pays for the gifts of 3.2 orders that already qualified. Tiers pay when they sit just above what most orders already hold.

## Questions

### Are tiered gifts profitable for supplement brands?

On these costs, with a travel-size bottle as the gift, two units and one gift keep $29.97 per order and three units and two gifts $47.05, against $11.69 for one unit. The tiers are profitable when they move buyers up; given to buyers already at a tier, they only cost the gift.

### What does a second gift tier cost supplement brands?

$11.44 on an order of three here, for two gifts, against $5.72 for the one gift of the first tier. The step from two units to three adds $17.08 of margin after it.
