Discounts & Coupons Guide: Tiered Volume Savings and Promo Codes

Learn how discount mechanisms work on idgaga, including automatic tiered quantity discounts and promo code redemption in your shopping cart.

Quick Answer

idgaga employs a transparent, automated pricing and discount engine that calculates totals in a strict 4-step sequence: Base Subtotal → Tiered Quantity Discount → Coupon Code Discount → Shipping Cost = Final Total.
