QSortby: Best Sellers & Upsell

QSortby keeps every collection ordered by what is actually selling: pick a signal - sales velocity, revenue, margin, conversion or trending - and new orders re-score it in seconds. You write the ranking rule in plain words, and preview the exact new order side by side before it publishes. Sold-out products sink and return on restock. The same ranking also feeds cart, bundle, popup, thank-you and in-checkout offers - and any sort can run as an A/B test against your current order.
