Levels Supplements Promo Codes & Coupons February 2026

Your Levels Supplements promo code likely isn't working because it's expired, not valid for items in your cart, or restricted to first-time buyers. These are common issues shoppers encounter when trying to use codes like KARINA.

Levels uses Shopify checkout, so codes automatically validate against cart contents. Expired codes or product-specific ones trigger rejection without detailed explanations. This often happens during sales when inventory changes.

To fix the issue:

1. Verify the code is current and active
2. Remove any ineligible items from your cart
3. Clear your browser cache or try using incognito mode
4. Enter the code exactly as shown in the "Discount Code" box at checkout and hit Apply

Pro tip: If you're a new customer, try codes like WELCOME15 first, as these tend to have higher success rates for first-time purchases.

No, Levels Supplements does not allow stacking multiple promo codes on a single order. Their Shopify system applies only one code per checkout, and attempting to add a second code will result in a "Code already applied" error.

This follows standard Shopify merchant practices to prevent discount abuse. When you have multiple codes available, you should:

1. Pick the best code for your order (like BOGO50 for 50% off whey products)
2. Enter it in checkout's single "Discount Code" field
3. Apply the code before completing payment

Pro tip: Compare code values in your cart preview before deciding which to use—a code like KARINA offering 20% storewide might be better than product-specific codes for most orders.

Levels Supplements promo codes generally do not apply to subscription products. Most codes like WILTON (20% off) will show "Not applicable to subscriptions" errors when applied to subscription orders.

Subscription products use separate discount logic, prioritizing recurring savings over one-time promo codes. To check if a code works with subscriptions:

1. Add the subscription item to your cart
2. Proceed to checkout
3. Try applying the code—if it fails, consider switching to a one-time purchase

Pro tip: Consider making a one-time purchase with a code like KARINA for an immediate 20% discount, then switch to a subscription for future orders to benefit from loyalty perks.

Enter your promo code in the "Discount Code" or "Promo Code" box on the mobile checkout screen, located right below the order summary. Mobile users sometimes miss this field due to the need to scroll down.

To apply a code on mobile:

1. Add items to your cart on levelsprotein.com mobile site
2. Tap the cart icon and proceed to checkout
3. Scroll down to find the "Discount Code" field under the subtotal
4. Paste your code (e.g., KARINA) and tap Apply—you'll see either a green success message or red error

Pro tip: Copy your promo code to your device's clipboard before starting checkout to avoid having to switch between apps or retype the code on a small screen.

Yes, Levels Supplements first-time customer promo codes like WELCOME15 or WILTON are restricted to new accounts only. These codes will show "Not for returning customers" errors when used on repeat orders.

These restrictions are triggered by email/IP detection in the Shopify system. First-time codes typically:

1. Exclude subscription products and sale items
2. Expire within 1-3 months
3. Only work with completely new accounts

Pro tip: For the best chance of success with first-time codes, clear your cookies or use a different device to ensure you're recognized as a new customer in their system.
