BST‑Frequently Bought Together vs Sell Plus Post Purchase Upsellfor Shopify (2026)
BST‑Frequently Bought Together and Sell Plus Post Purchase Upsell are both Shopify apps designed to increase revenue through upselling and cross-selling. BST‑Frequently Bought Together focuses on pre-purchase product bundling with AI-powered recommendations and customizable, mobile-first widgets. It emphasizes visual appeal and ease of integration, targeting merchants looking for a visually appealing and automated way to present complementary products on product pages. In contrast, Sell Plus Post Purchase Upsell, with limited data available, appears to concentrate on increasing revenue through post-purchase upselling, which presents offers after the initial purchase is completed. The main difference lies in the approach: BST emphasizes upfront bundling using AI and visual customization to influence pre-purchase decisions, while Sell Plus (based on its name) uses upselling opportunities *after* a customer has committed to a purchase. BST appears more mature based on its number of reviews, indicating a broader user base and potentially more comprehensive feature set although that cannot be confirmed from the given data. They both target revenue maximization, but their strategies cater to different points in the customer journey.

Our Verdict
For merchants looking for a comprehensive, visually driven solution to bundle frequently bought items *before* the customer checks out, BST‑Frequently Bought Together is the clear choice. Its AI-powered recommendations, extensive customization options, and a significantly larger number of positive reviews suggest a more mature and reliable product. Its focus on mobile-first design is important in 2026.
Sell Plus Post Purchase Upsell may be suitable for merchants specifically targeting post-purchase upselling strategies. However, the lack of information and limited reviews make it difficult to assess its quality and effectiveness compared to BST. Given the disparity in reviews, choosing BST represents a lower risk for merchants seeking to boost sales via product bundles in 2026 unless a post-purchase upsell is a very specific need.
