Shipping gets real: orders share vans

Shipping a crate of milk used to cost as much as chartering the whole van — the full route's fuel landed on every order, however small. That's fixed, in both directions:

• Pay for the van space you use. A delivery van carries 5 tonnes / 25 m³. Each order's fuel surcharge now covers its share of the van's road burn (minimum 5% of a trip), plus the weight and bulk it actually adds. Small deliveries get dramatically cheaper; multi-van hauls now correctly pay road fuel for every van they fill.
• Orders ride together. At dispatch, pending orders from the same origin to the same city are grouped into shared vans — ten small orders no longer occupy ten depot bays, and your fleet stretches much further.

Carrier rate cards are unchanged — this only fixes how fuel and van capacity are accounted. Expect supply costs for small restocks to drop sharply.
