Bulk buyers do not want to add twelve units one by one. They want the case. Kolli puts a pack selector on the product page: one tap picks the pack, the quantity follows, and the saving lands at checkout as a real order discount, not a rewritten price. Build a bundle in minutes: pick products, add quantity tiers, choose a percentage, an amount off or a fixed unit price, publish. The block inherits your theme font and colour, and every bundle runs through one automatic discount.

• Quantity tiers on the product page — unit price, total and saving in one tap
• Percentage, amount off or a fixed unit price, with .90 or .99 rounding
• Real order discount at checkout — clean orders and refunds, no draft orders
• One automatic discount for every offer, not one discount per offer
• Theme app extension — nothing to edit in your theme, about 3 KB added
