Coupon Types Explained
Understanding coupon types helps you choose the right code for each purchase. Welcome coupons are perfect for testing new sellers, while volume coupons reward larger carts.

Coupon Etiquette and Best Practices
Smart coupon usage goes beyond finding codes. Test every coupon before checkout by adding it to your cart early. Never share VIP or exclusive codes publicly — sellers track code usage and may revoke privileges if codes leak beyond intended audiences. Document your savings to identify which sellers consistently offer the best value.
