The Wonder Weeks Promo Codes & Coupons February 2026

To register your Back to You book code and access the workout app:

1. Visit thewonderweeks.com/bty
2. Enter your unique code from your physical Back To You book
3. Create an account to unlock free access to the workout app
4. Log into the app via the "I have the book" option using your email and password

Note that this process is specifically for book buyers and is separate from the full digital subscription app. Codes are one-time use per account and tied to your book's unique serial number.

Pro tip: Take a screenshot of your book code before scratching it off, as some users report the ink can fade over time.

If your verification code isn't working, it's likely due to a broken verification email link, which is a common app glitch where auto-verification fails. To manually enter your code:

1. On the app's email verify screen, tap the "Help" button in the top-right corner
2. Input the 6-digit code from the email exactly as shown (case-sensitive, no spaces)
3. If you still get an error message like "Code expired" or "Invalid," restart the app
4. Check your spam folder for a resend if needed

Verification codes typically expire after 24-48 hours. If you continue to have issues, contact support@thewonderweeks.com.

Pro tip: Use the app's "resend verification" option before trying the Help button to avoid manual entry hassles.

Promo codes can only be applied at checkout for one-time purchases like books on thewonderweeks.com, not for Back To You subscriptions which are processed through app stores. Book codes are registered after purchase at thewonderweeks.com/bty for free app access.

Subscriptions (monthly/quarterly/yearly) don't have promo code fields since they're billed through app stores, which is why you might see "code not applicable" errors if you try to use them. Book purchases typically take 7-14 days for shipping.

Pro tip: Consider buying the book+app bundle for "free" workouts instead of a subscription, which can save you approximately $35 compared to the yearly plan.

If you receive an "Invalid code" or "Already redeemed" error when trying to redeem your book code:

1. Make sure you're redeeming at thewonderweeks.com/bty (not in the app)
2. Log out and log back in on the website
3. Re-enter the code exactly as it appears in your book
4. Select "I have the book" in the app after completing registration

Remember that codes are single-use and typically valid for 6-12 months after purchase. If you continue to have issues, email support with your order number.

Pro tip: Try redeeming on a desktop browser first, as mobile site glitches can sometimes block redemptions.

Your promo code might not be working for several reasons:

• It may have expired (most codes last 3-30 days)
• There could be typos in your entry
• The code might be excluded from subscriptions or app store items
• Verified discount codes (like 45% off) typically work only on physical products like books

If you see "Code expired" or "Not valid" during checkout, try clearing your cache or using an incognito browser window.

Pro tip: Copy and paste the code directly from the source site and apply it before entering payment information to avoid hidden characters that can cause failures.

No, The Wonder Weeks checkout accepts only one promo code per order. Attempting to use multiple codes will trigger an "Only one code allowed" error message.

When choosing which code to use, prioritize the one with the highest discount percentage (such as 45% off). Remember that these codes apply to books and physical products, not app subscriptions.

Pro tip: You can maximize savings by applying a code to a book purchase, then using the included free app access—eliminating the need for multiple codes.

No, promo codes don't apply to app subscriptions because they're billed through Apple/Google Play, which don't provide a promo code field. Promo codes are only valid for one-time purchases on the website, such as books.

If you try to use a promo code during in-app upgrades, you'll likely see a "Not applicable" message. Subscriptions typically offer 7-day trials instead of discount codes, with yearly plans priced around $34.99.

Pro tip: If you decide to subscribe after your trial, opt for the yearly Back To You subscription for the best value over monthly, especially since the program spans 9 months.

If you receive a "Promo code expired" error message, you should:

1. Request a fresh code from the original source (such as coupon websites)
2. Check the website footer for a list of currently active codes
3. Email customer support to ask for a possible extension
4. Look for new promotional offers that may have replaced the expired code

Most promo codes expire within 3-30 days, and unfortunately, you can't retroactively apply them to previous purchases.

Pro tip: Bookmark verified coupon pages and check them regularly, especially on Thursdays when new codes are often released after promotional cycles.
