Verdict on Moon

Moon Bundles is one of the best-value bundle apps on Shopify, combining bundles, cart drawer upsells, post-purchase offers, and volume discounts into a single install.

The revenue cap pricing model is transparent — you only upgrade when your bundles are actually making money.

Verdict on Farabiulder

Farabiulder brings Pinduoduo-style group buying to Shopify — a viral growth model that is genuinely different from typical upsell apps. The free plan lets you test the concept, and auto-refunds for failed groups protect customers. Very new with only 2 reviews, but innovative.
