# BOM (Bill of Materials) — NowYouSea Station
|
||
|
||
> **Goal:** cost a *low-cost* acoustic station using **current online TTC prices** (France/EU when possible), including **shipping** so we don’t omit it.
|
||
>
|
||
> **Shipping assumption:** delivery to **Vannes (56000), France** (placeholder address: *1 place de la République*).
