POR-15 Promo Codes & Coupons February 2026

Your POR-15 promo code likely isn't working due to expiration, minimum order requirements like $150+, or exclusions on sale items. Most POR-15 codes are site-wide but often have limitations such as one-time use or military-only via GovX verification.

Here's how to fix the issue:

1. Copy a fresh code from a reliable coupon site (like SimplyCodes)
2. Add items to cart on por15.com, proceed to checkout
3. Paste in the "Promo Code" field under order summary—refresh if no update
4. Check for minimums or exclusions before payment as codes auto-validate in real-time

Pro tip: Clear browser cookies or use incognito mode—POR-15 tracks sessions, and cached data often blocks code detection.

No, POR-15 does not allow combining multiple promo codes on one order; their system accepts only one per checkout. This single-code policy is typical for POR-15 to prevent stacking abuse. Common scenario: Shoppers add a percentage off code then try to add free shipping, hitting rejection at validation. Military GovX codes also can't stack with other promotions.

Here's a workaround to maximize savings:

1. Test highest-value code first (such as 20% off)
2. Apply at checkout's promo field; it overrides others
3. For bundles like rust kits, look for code-specific ones like 10RUST

Pro tip: Stack a POR-15 code with free shipping thresholds (often $100+ orders) by bulking rust prevention kits—maximizes savings without violating their policy.

Yes, most POR-15 promo codes are site-wide and apply to all products including rust prevention kits like the 3-step Stop Rust System. However, exclusions may apply to sale/clearance items or orders below minimum thresholds ($150 for some 10% codes). POR-15 conventions often favor kits in code descriptions (e.g., 10RUST for systems).

Here's how to check if a code works for rust kits:

1. Add rust kit to cart on por15.com
2. Enter code at checkout summary
3. Review discount line—if "not applicable," swap for a verified site-wide code like 15% off

Pro tip: Look for codes with "rust" in their descriptions before buying kits—targeted codes like 10RUST save 10% specifically on rust prevention products, sometimes beating generic site-wide discounts.

Enter your promo code in the dedicated "Promo Code" or "Discount Code" field located under the order summary on the POR-15 mobile checkout page, just above the payment section. Mobile users often miss it due to the swipe-heavy design, as the field may not be visible until scrolling past shipping information.

Here's how to find and use it:

1. Add items, tap cart icon
2. Select "Checkout" > enter shipping
3. Scroll to "Order Summary" > tap "Promo Code" box
4. Paste your code (e.g., RUST10), hit apply—green confirmation shows discount

Pro tip: Zoom out on mobile for full summary view—POR-15 hides the field on smaller screens, saving you from frantic refreshes.
