Your Margin Gate, Written First: Side Hustle Ecommerce
List a sourced SKU only after you write the margin gate in your own numbers and the source page you used. A fifty-percent rule is not on this page.

Blue ocean here means a gate you wrote, not a slogan. If the costs you can see miss the gate, you do not list.

The gate
- Your minimum remainder after the costs you can see.
- The source: the product page or supplier page, with the date.
- A no, written, when the remainder misses the gate.
Alliance terms
Coupon and merchant rows are the commission map.
