Whether the threshold counts tax and coupons is covered in Order value, taxes, and currency.
Offering free shipping once an order reaches a certain amount is one of the most effective ways to increase the average order value. Here is how to set it up with Weight Based Shipping, from a simple flat-rate setup to weight-aware variations.
Scenario A Flat rate below the threshold
The classic setup: charge a flat rate, and ship free once the order subtotal reaches $100.
Two rules split the price scale. The first matches orders valued $100.00 and over and charges nothing; the second matches orders under $100.00 and charges the flat rate. The free rule isn't decorative: with no matching rule at all, the method would disappear from the checkout instead of becoming free.
Example #1
Cart: Shirt ($70), Pants ($40).
Subtotal: $110.
Result: $110 ≥ $100, so shipping is free.
Example #2
Cart: Shirt ($70).
Subtotal: $70.
Result: $70 < $100, so shipping costs $5.00.
Scenario B Weight-based rates below the threshold
Below the threshold, shipping does not have to be flat. Here the regular price grows with the cart weight: each weight bracket carries the same under-$100.00 value condition, so the rates apply only below the threshold, and the free rule is the only match above it.
Example #1
Cart: $110 total, 7 kg.
Result: $110 ≥ $100, so shipping is free regardless of the weight.
Example #2
Cart: $80 total, 3 kg.
Result: $80 < $100, so the weight rates apply: 3 kg falls into the 2–5 kg range, $3.75.
Scenario C No free shipping for heavy orders
Free shipping on a big order can still be a loss if the order is heavy. To cap it, add a weight condition to the free shipping rule: conditions within a rule must all be met for the rule to apply, so orders valued $100.00 and over now ship free only when they weigh up to 10 kg. The paid rules cover the rest of the grid: any order under the amount, and heavy orders over it — $5.00 either way.
Example #1
Cart: $110 total, 8 kg.
Result: both conditions are met ($110 ≥ $100, 8 kg ≤ 10 kg), so shipping is free.
Example #2
Cart: $110 total, 15 kg.
Result: the weight condition fails (15 kg > 10 kg), so shipping costs $5.00 despite the order value.
Scenario D Free rule first, with Stop
The Pro edition offers a second shape of the same table. Instead of bounding every paid rule with an under-$100.00 condition, put the free rule first and give it the Stop mod: once it matches, no rule below it is looked at, so the paid rules stay unconditional. With several weight brackets below the threshold that is one condition instead of one per bracket. The order matters — the free rule must sit above the paid ones.
Example #1
Cart: Shirt ($70), Pants ($40).
Subtotal: $110.
Result: $110 ≥ $100, so the free rule matches and ends the evaluation: shipping is free.
Example #2
Cart: Shirt ($70).
Subtotal: $70.
Result: $70 < $100, so the free rule does not match and the $5.00 rule below applies.
