TierUp

TierUp adds "buy more, save more" pricing to any Shopify product — 1 for $50, 3 for $45 each, 6 for $40 each. The discount applies automatically at checkout, a tier table renders on the product page, and a live nudge tells shoppers "add 2 more to save $X."

Built on native Shopify Functions (not draft orders), so Google Analytics, Meta Pixel, Shop Pay and Apple Pay keep working, and your 3PL still sees the same SKUs. Most volume-discount apps in the Shopify ecosystem charge $10-30/month or take a percentage of the revenue they help you earn. TierUp doesn't. Free forever — no fees, no revenue share, no cap.
