CartClimb ‑ Free Gift & Upsell

CartClimb grows cart size from product page to checkout. A real-time reward bar pushes shoppers toward free shipping, a percentage discount, and a free gift — stack up to 3 tiers, with the gift auto-added at $0 and the discount applied at checkout. Add product-page and Shopify Plus checkout upsells, plus a promo banner with countdowns and scheduled sales. Smart controls block gift misuse, support local currencies + geo-targeting, flag theme issues, and work on any theme or device.
