The Trailer Parts Outlet Promo Codes & Coupons February 2026

Trailer Parts Outlet promo codes typically do not work on clearance or sale items. Their system is designed to exclude already discounted products to prevent excessive markdowns.

When attempting to use promo codes like NEW5 or TRAIL5 on items from the specials collection, you'll likely encounter error messages stating "This promo code cannot be applied to sale items" during checkout. This is standard practice for trailer parts retailers, where sale prices (which can reach up to 25% off) are considered final to maintain margins on high-volume items like axles and wheels.

If you want to use a promo code successfully:

1. Remove any sale items from your cart
2. Apply your code (such as SAVE5 for 5% off) in the checkout promo box
3. Check that your subtotal updates to reflect the discount
4. If needed, place a separate order for sale items

Note that promo codes also typically exclude volume discounts (like 4-5% off orders over $9,000) and free gift promotions.

Pro tip: For maximum savings, use codes like WELCOME5 on full-price items first, then shop the specials page for additional deals, especially during holiday promotions like Memorial Day.

No, The Trailer Parts Outlet only allows one promo code per order. If you attempt to enter multiple codes, the checkout system will display an error message like "Only one discount code allowed."

This is standard policy for the merchant, as reported across various coupon sites. When customers try to stack codes (such as 10OFF with CART3), the system will only apply the first code entered. This includes newsletter sign-up codes like WAVE3 and one-time use email codes - none can be combined with other offers. These restrictions apply across the entire website, with no exceptions even for VIP or military discount offers.

To get the best discount:

1. Test different codes one at a time in the checkout's promo field
2. Choose the one that gives you the highest discount (typically up to 10-15% off)
3. Clear your cart and start over if your testing doesn't work as expected
4. Consider qualifying for tiered order discounts (such as 4% off orders over $9,000) if available
