Mission Allergy Promo Codes & Coupons February 2026

Your Mission Allergy coupon likely isn't working due to one of several common issues: it may have expired, apply only to specific promoted items, or not be valid for the products in your cart. Common error messages include "Invalid code" or "Code not applicable to this order."

Mission Allergy codes often have restrictions such as specific eligible items or minimum spend requirements (e.g., $75+ for free gifts). Most codes are limited to one per order, and free shipping offers typically apply to U.S. orders only. Issues can occur during checkout if your cart total drops below required thresholds after adding items, or if you're trying to use a code on ineligible products.

To fix coupon code issues:

1. Verify the code is current on coupon sites like SimplyCodes.
2. Make sure to update cart quantities before entering the promo code.
3. Apply the code at the designated field in your cart at missionallergy.com/viewcart.
4. Check that your items meet any eligibility requirements for the specific code.

Pro tip: Try clearing your browser cookies and using incognito mode, as cached information can sometimes interfere with proper code application.

No, Mission Allergy allows only one promo code per order. This policy is reflected in their checkout system at missionallergy.com/viewcart, which provides a single promo code field and will display an error like "Code already applied" if you attempt to enter a second code.

While some benefits like free gifts (on orders $75+) or shipping deals may automatically apply, these cannot be combined with percentage-off codes.

To maximize your savings:

1. Compare available codes and select the one offering the highest value (e.g., a 60% off promotion might save more than free shipping).
2. Build your cart to meet any thresholds for automatic benefits first.
3. Consider placing separate orders if that would allow you to use multiple valuable codes.

Pro tip: Site-wide percentage-off codes (typically 15-25%) often provide better overall savings than item-specific promotions.

Yes, many Mission Allergy promo codes apply to their allergy-free bedding products, including pillows and comforters. These items frequently qualify for discounts ranging from 15-45% off with codes like OPE15.

However, some promotional codes may have exclusions or apply only to specific promoted items, so it's important to verify eligibility before completing your purchase.

To apply a promo code to bedding products:

1. Add your desired allergy-free bedding items to your cart.
2. Enter the promo code in the designated field at checkout.
3. Confirm the discount appears before finalizing your payment.

Pro tip: Look for opportunities to combine percentage discounts with free shipping offers on larger bedding purchases, as Mission Allergy sometimes offers free FedEx shipping on orders over $400.

Yes, Mission Allergy offers special promotions for first-time customers, including a reported 50% off code specifically for first purchases. New customers can also take advantage of general site-wide codes offering 20-25% discounts.

These first-time purchase codes are typically detected automatically at checkout for new accounts. If you're returning to the site with cookies enabled, you might see an error message indicating you're not eligible for first-time offers.

To claim first-time customer discounts:

1. Visit missionallergy.com using an incognito browser window to ensure you're recognized as a new visitor.
2. Add items to your cart and apply the first-time buyer code at checkout.
