Upsell sales page for water company

Ever finished checking out and got hit with an offer too good to skip? That’s exactly what blk. Water nails here. After payment, they hit you with a post-purchase upsell that feels like a no-brainer.

The Smart Design Behind It

• Shows the retail price, discounted price, and savings side by side.
• Creates instant FOMO with a “limited time offer.”
• Payment info is already saved, so buying again is literally one click away.

Why It Works

• Anchoring: Seeing $17.99 makes $4 look like pocket change.
• Urgency: “Limited time” lights a fire.
• Convenience: No re-entering info reduces friction.
• Reciprocity: “You trusted us once, here’s another deal.”

Examples

• Amazon’s “Add this to your order” pop-ups boost order value by 10–15%.
• McDonald’s “Would you like fries with that?” adds billions annually.
• Shopify stores using one-click upsells see up to 30% more revenue per customer.
