Pack pricing: sum, markup, markdown, and .99 rounding

By default, a pre pack price is the sum of its component size prices × quantities. Pricing rules let you go further: add a wholesale markup, discount the pack vs open stock, round to charm prices like .99, and optionally set compare-at when the pack is discounted.

Pricing modes

• Sum of components — pack price follows unit prices exactly.
• Fixed amount adjust — increase or decrease by a dollar amount after the sum.
• Percentage adjust — increase or decrease by a percent of the component sum.

Charm pricing and compare-at

Enable round-to-.99 when you want clean retail endings. When a rule discounts the pack below the component sum, you can set compare-at so the storefront shows the savings clearly — especially useful with the customizable storefront embed.

Reapply to existing packs

After you change shop pricing settings, reapply rules to existing packs so older variants stay consistent with new products. Combine this with Manage Pre Packs when you need to spot-check a few SKUs after a pricing change.

Inventory still follows components

Pricing rules change the pack’s sell price. Available quantity is still limited by the scarcest component size in the ratio — so you never oversell a size you cannot fulfill.
