First Day Promo Codes & Coupons September 2025

This message usually means the code is either expired, restricted to certain users, or not valid for the items in your cart—even if you think you meet the requirements.

First Day often issues codes that are single-use, limited to new customers, or tied to specific products or subscription plans. For example, some codes like SAVEHEALTH are only valid for first-time orders or for a first month’s subscription. If you’ve used a similar code before, or if your email/account has already redeemed a new customer offer, the system may block the code. Codes can also be region-specific or temporarily disabled during sitewide sales.

To resolve this:

• Double-check the code’s terms (product, user, and timing restrictions).
• Try using a different email if you’re a new customer but have shopped before.
• Remove excluded items from your cart and reapply the code.
• Make sure you’re not combining codes, as First Day typically allows only one per order.

Pro tip: Always check the code’s fine print and test codes from verified sources with high recent success rates for the best chance of savings.

If your discount isn’t appearing, the code may not be valid for your order, or there could be a technical issue at checkout.

Common reasons include: the code is expired, only applies to specific products (like subscriptions, not one-time purchases), or you’ve already used a similar code before. Sometimes, the discount only appears after you enter all required information (like shipping details), or if you’re logged in with the correct account.

Step-by-step:

1. Confirm the code is active and matches your order type.
2. Ensure your cart meets any minimum purchase or product requirements.
3. Try refreshing the page or using a different browser/device.
4. If the code still doesn’t work, remove and re-add items, then reapply the code.

Pro tip: Use community-verified codes and watch for real-time feedback on which codes are currently working best for your specific order.

The most common reasons are: code expiration, one-time use limits, product/category restrictions, and account eligibility.

• Expired codes: Most codes have clear expiration dates, often listed on coupon sites or in the code details.
• One-time use: Many First Day codes are single-use per customer or email, especially new customer offers.
• Product restrictions: Some codes only apply to subscriptions, specific bundles, or exclude sale items.
• Account restrictions: Codes may only work for new customers or first-time purchases.

To check:

• Look for expiration dates and usage terms in the code details.
• Try applying the code in a private/incognito browser or with a new account.
• Remove excluded items and test the code on eligible products.

Pro tip: Track which codes have high recent success rates and always read the code’s terms before applying to avoid frustration.

Yes, First Day’s checkout typically displays clear error messages such as “This code is not available for you right now,” “Code expired,” or “Code not valid for selected items.”

• “This code is not available for you right now” usually means you’re not eligible (e.g., not a new customer, or already used the code).
• “Code expired” indicates the code is no longer valid.
• “Code not valid for selected items” means your cart doesn’t meet the code’s product or category requirements.

These prompts help you quickly identify the issue so you can adjust your cart or try a different code.

Pro tip: If you see a vague error, double-check your cart contents and eligibility, and try reapplying the code after logging out and back in.

Your code may not work due to expiration, single-use limits, product restrictions, or account eligibility.

First Day codes often have strict terms—many are for new customers only, single-use, or tied to specific products or subscriptions. If you’ve used a similar code before, or your cart contains ineligible items, the code will fail. Technical glitches (like browser issues) can also prevent codes from applying.

To fix:

1. Check the code’s terms and expiration date.
2. Remove any ineligible items from your cart.
3. Try a different code or use a new email/account if possible.
4. Refresh your browser or try a different device.

Pro tip: Use codes from trusted sources with recent success reports, and always review the code’s restrictions before checkout.

First Day only allows one promo code per order; stacking multiple codes is not permitted.

This is a common policy for the brand, especially since many codes are for new customers or single-use only. Attempting to enter a second code will typically override the first, or you’ll see an error message.

Pro tip: Choose the code with the highest discount or best fit for your order, and check for additional sitewide sales or free shipping offers to maximize your savings.
