Fast Bundle review

Fast Bundle (listed as FBP: Fast Bundles & Upsell) packs more bundle formats into one app than most rivals here. Its listing covers mix and match bundles, fixed bundles, custom kits and build your own bundles through Bundle Builder, plus BOGO, Buy X Get Y, free gifts with purchase, product add-ons, volume discounts and AI-powered frequently bought together offers. Offers can run on product pages and on Shopify POS. Every paid plan has the same features, including unlimited AI frequently bought together and an AI bundle image generator, so the only variable is bundle sales: Standard (1K) costs $19 a month up to $1,000 of monthly bundle sales, Standard (3K) $49 up to $3,000 and Standard (10K) $139 up to $10,000. Auto Bundle Detection is an optional add-on at $49 a month. The listing showed a 5.0 rating from 3,667 reviews. It ranks below Kaching Bundles on value because its entry price is higher and it is free only for development stores.
