Verdict on Pumper

Pumper Bundles is the go-to app for stores that rely on quantity-based pricing, volume discounts, and bundle deals. With 2,700+ reviews and a 4.9 rating, it has proven itself at scale. The free plan with up to $300 in extra revenue makes it accessible to new stores, while the Unlimited plan caps costs for high-volume merchants. Where Pumper truly shines is its breadth of integrations — it works with nearly every major cart drawer and page builder on Shopify. The trade-off is that it focuses purely on bundles and discounts, so you'll need a separate app for cart drawer upsells or post-purchase funnels.

Key Features

• Gamified, fully customizable multi-step bundle layouts with pre-built templates
• Supports multipacks, mix-and-match, variant bundles, build-a-box, gift boxes, and subscription bundles
• Multiple discount rules including tiered pricing, fixed-price bundles, and free gift thresholds
• Developer-friendly with open SDKs for completely custom bundle designs
• Inventory sync with all 3PL providers and built-in performance analytics

Verdict on EB

Easy Bundle Builder is the premium choice for merchants who need deeply customizable, gamified bundle experiences. The multi-step flow and build-a-box capabilities are best-in-class, and the SDK access makes it the top pick for stores with developer resources. The pricing is higher than competitors, but justified for stores doing serious bundle revenue. The free Starter plan lets you test the waters before committing.
