Shipping Rates & Weights

Table shipping rates for any delivery method — the courier costs 10 on
small orders, 5 over 50 and becomes free over 150. Or charge by weight.

Rate tiers

For each delivery method add tiers measured by one of:

• cart subtotal — classic spend-based pricing;
• item count — e.g. flat 5 per parcel up to 3 items, 8 above;
• total weight — needs product weights (see below).

A tier is from (inclusive) — to (exclusive) → cost. Empty to means
"and above". At checkout the first tier whose range covers the cart wins;
with no matching tier the method keeps its base cost from Shop → Shipping.
The core method's "free from" threshold still applies before the tiers.

Example (courier):

0 – 50    → 10
50 – 150  → 5
150 – ∞   → 0

Product weights

The plugin adds a weight (kg) field to shop products and a bulk editor
(Shipping Rates → Product weights): a paginated table of products with
inline inputs, saved in one click. Weight tiers and the core "by weight"
delivery mode use these values; products without a weight count as 0.

Requirements

Shop plugin 1.3.0 or newer (the shop.shipping.cost checkout hook).
