What happened

Both apps put a volume-discount table under the price and both do it well — this is a close call decided by pricing model and by whether you need free-gift logic. Kaching carries the larger review base and the cleaner default widget. Pumper adds gift-with-purchase thresholds, which turn a discount into a perceived bonus and protect margin better than a straight percentage off. The one thing to test in both: how the discount interacts with codes and with Shop Pay before you run a sale on it.

Round by round

Scored on what decides it

Kaching Bundles App & Upsells takes 3 rounds, Pumper Bundles Quantity Breaks takes 2, with 0 tied.

AxisKaching Bundles App & UpsellsPumper Bundles Quantity BreaksWhy
Validation Wins — 5,200+ reviews at 5.0 against 3,200+ at 4.9 — both excellent, Kaching ahead on volume.
Free gift logic — Wins Pumper's gift-with-purchase thresholds are the reason to choose it. A free gift often outperforms an equivalent discount because it does not reset the shopper's price anchor.
Pricing model — Wins Pumper offers a free plan. Kaching is 'free to install', which means usage-based charges that grow with order volume.
Widget design Wins — Kaching's quantity-break block reads more cleanly on mobile out of the box, which matters because this widget sits directly under the price.
Managing many offers Wins — Pumper's admin becomes dense once you are running several concurrent offers across collections.
