The Tiered Discount Architect

Act as a behavioral economist. Help me design a tiered spending offer that systematically incentivizes customers to increase their cart value.

• Base Product Price Point: [e.g., "Our products range from $30 to $100"]
• Average Order Value (AOV) Goal: [e.g., "Increase AOV from $75 to $110"]

Task: Create a 3-tier discount structure. Define the spend thresholds and corresponding discounts (e.g., "Spend $100, get 15% off; Spend $150, get 20% off; Spend $200, get 25% off"). Explain the psychological principle behind each tier and calculate the new, post-discount total a customer would need to spend to reach the next tier.
