Under the Weather Promo Codes & Coupons February 2026

Promo codes at Under the Weather often show as invalid for several common reasons. These include expired codes, codes that have already been used, or codes that don't apply to the items in your cart. Common issues include mistyping the code (remember they may be case-sensitive), attempting to use expired promotions, or not meeting specific requirements like minimum purchase amounts.

To fix the issue:

1. Double-check the spelling and expiration date of your code on the official Under the Weather website or reputable coupon sites.
2. Clear your browser cache or try using incognito mode, as checkout glitches can occur during high-traffic sales periods.
3. Test alternative codes that might be currently active, such as percentage-off or free shipping offers.
4. Contact Under the Weather customer support if you're using a single-use email code that should be valid.

Note that some codes exclude certain products like specific pods or gift cards, and free shipping typically requires a minimum purchase of $20 or more.

Pro tip: Copy-paste codes directly from verified coupon sites to avoid typos and check recent user reports to confirm if a code is still working.

No, Under the Weather does not allow combining multiple promo codes on one order. Their checkout system accepts only one promo code per transaction. If you try to apply multiple codes, you'll likely receive an "Invalid code" error message, especially when attempting to combine free shipping codes with percentage-off discounts.

When checking out, you'll need to choose the single code that provides the best value for your specific order. For example, a 20% off sitewide code might save you more than a free shipping offer on orders over $49.

Military discounts (ranging from 10-25% off) are available but must be verified separately and cannot be combined with other promotional offers.

Pro tip: Prioritize the highest-value code for your order (such as a 50% BOGO offer over a 20% discount) and consider subscribing to Under the Weather's email list for exclusive first-purchase codes.

Under the Weather promo codes typically do not apply to sale or clearance items. Products that are already discounted, such as items in their up-to-60% off sections or marked as "while supplies last," are usually excluded from additional promotional discounts. When attempting to apply codes to these items, you may see error messages like "Not eligible for discount" at checkout.

The checkout system automatically identifies items flagged as "sale" products, and sitewide codes (like 20% off offers) will skip these clearance items. There are occasional exceptions where specific promotions might allow discounts on sale items, but you should verify this in your cart preview before completing your purchase.

Pro tip: If you're purchasing a mix of full-price and clearance items, add the non-sale products to your cart first, apply your promo code, and then add the clearance items to avoid issues with your discount.

Under the Weather Pet promo codes generally work on subscription pet supplement orders at undertheweatherpet.com, but there are some limitations. Codes like PETLOVE20 (20% off sitewide) can typically be applied to subscription orders, but they may exclude initial trial offers or automatic renewals according to the company's terms.

To apply a promo code to a subscription order:

1. Add your pet supplements to your cart and select the subscription option at checkout.
2. Enter your promo code before confirming the recurring order.
3. Note that the discount usually applies only to your first subscription cycle; future shipments may require re-entering a valid code.

Restrictions may apply, and some codes cannot be combined with subscription-specific free shipping offers.

Pro tip: Start your subscription with a verified promo code for the best initial savings, then manage your subscription as needed for ongoing value.

If your Under the Weather promo code was accepted but the discount isn't showing in your final total, this could be due to several factors. Common issues include taxes or shipping costs offsetting the discount, cart minimums not being met (such as the $20 minimum for free shipping codes), or the discount applying only to specific items in your cart.

To resolve this issue:

1. Review your complete order summary—the discount may be showing on the subtotal but not affecting shipping or tax amounts.
2. Try removing and re-adding items to your cart, then reapply the code.
3. Switch browsers or clear your cache if you suspect a technical glitch.
4. Check the email order preview to verify how the discount is being applied.

Pro tip: Take a screenshot of your checkout page before completing payment so you have documentation if you need to contact customer service about a discount that wasn't properly applied.
