About MarginNook
MarginNook is an independent educational project for small physical-product sellers who want to understand pricing, promotions, and channel costs.
Our initial research focuses on US Etsy seller scenarios, with Shopify considered as an additional channel. We use official platform information and clearly labeled hypothetical examples. We do not claim to operate an Etsy shop or to hold professional financial credentials.
What you can expect
Focused guides, reproducible arithmetic, explicit limitations, and recommendations that include the option to use a free approach or buy nothing. AI assists drafting and engineering; it is not represented as a seller with lived experience.
We do not promise sales, ranking, platform approval, or profit. Platform names identify the services being discussed and imply no endorsement.
