Shipping costs divide by order value — the ₹70 freight on a ₹300 order is 23%; on ₹900 it's 8%. Every seller knows this; the levers that push carts up the curve are worth their own playbook.
The threshold mechanic
'Free shipping above ₹699' when AOV is ₹540 pulls carts up — customers add a ₹160 item to save ₹70 freight (the irrational-seeming math that actually works). The threshold price-anchors the upsell; set it ~20% above current AOV and watch the lift.
The bundle play
'Buy any 3, ship free' converts freight economics into merchandising — three ₹200 items share one parcel's freight and the customer's ₹70 saving. The bundle is cheaper for them, denser for you, and AOV triples on the same order.
The unlock add-ons
Low-price add-on items exist to fill thresholds — the ₹99 phone charm that completes 'free shipping'. Checkout nudges 'add ₹85 more for free shipping' do the suggestion; small-catalogue sellers keep a 'threshold-fillers' collection for exactly this.
The combined math
Threshold lift + bundle share + add-on fill: sellers running all three report AOV lifts of 20–40% — which, at fixed freight, is margin appearing from the shipping line.
Pakka Parcel automates exactly this — the pipeline from order to AWB without the manual steps.
