Verdict on SwiftBundle

SwiftBundle is a compelling free option with a Built for Shopify badge — a rare combination. The unlimited bundle creation with real-time inventory sync and live cart previews puts it on par with paid competitors. It is still very new, but the quality indicators (Built for Shopify badge, OS 2.0 compatibility, checkout extensions) suggest serious development quality. Worth installing to test alongside your current bundle solution.

Verdict on Boomerang

Boomerang takes a unique approach to conversion — intercepting bouncing visitors and redirecting them to a targeted offer. The concept is sound but at $29-$199/month with only 9 reviews, it is expensive and unproven. The 30-day free trial reduces risk.
