Free-shipping thresholds & volume pricing

Set the free-shipping bar just above your real AOV, show a progress bar to close the gap, and offer 2/3-packs as the easy way over, then margin-check every bundle so free shipping never eats your contribution.

Free shipping over a threshold is the most reliable nudge in e-commerce, but only when the threshold is set from your real AOV (roughly 15-25% above it, verified against your order spread) and the math still leaves you a margin. Pair it with a cart progress bar that turns the threshold into a concrete, closeable gap, and with volume pricing (2-packs, 3-packs) that clears the bar in one click. Then margin-check the threshold order and each bundle so absorbing the shipping doesn't sink your contribution. AI does the arithmetic on your numbers; you supply AOV, shipping cost, and margin.
