MET-Rx Promo Codes & Coupons February 2026

Invalid code errors typically occur when the code has expired, doesn't apply to your specific items, or has usage limits that have been reached. MET-Rx promo codes are frequently rotated, and many codes listed online become inactive after a few months of use.

Common reasons your code won't work:

The code may have specific restrictions—some apply only to orders over a certain amount (like $50, $59, or $99 minimums), only to certain product categories, or only to first-time customers. Check the code's details carefully before entering it. Additionally, if a code shows "used 75 times" or similar language, it may have reached its redemption limit. Timing matters too; codes last used several months ago are less likely to be active than those used within the past week.

Step-by-step troubleshooting:

1. Verify the code's last-used date—prioritize codes used within the past 1-2 weeks
2. Check if there's a minimum order requirement and ensure your cart meets it
3. Confirm the code applies to your product category (some are limited to specific items like RTD shakes or performance powders)
4. Clear your browser cache and try again, as checkout systems sometimes cache expired codes
5. Try a different verified code from the same source to rule out a broader checkout issue

Pro tip: Use codes that show "Last used" within the past week, as these have the highest success rate—avoid codes last used more than 3 months ago, as they're likely expired.

You cannot combine additional promo codes with subscription orders on MET-Rx. Subscriptions already include a built-in 10% discount, and the site explicitly states "no additional promotional codes can" be applied.

How subscription discounts work:

When you set up a recurring subscription order, you automatically receive 10% off that order. If your subscription total exceeds $85, you also get free shipping included. This is a fixed benefit that replaces any other promotional codes—you can't layer a 15% or 20% code on top of the subscription discount.

Why this policy exists:

Subscription programs are designed to offer loyalty pricing that's already discounted. Allowing code stacking would essentially let customers combine multiple discounts, which retailers typically prevent to maintain margin control. This is standard practice across most supplement and nutrition retailers.

What you should do instead:

If you're considering a subscription, calculate whether the automatic 10% + free shipping (on orders over $85) beats what you'd get with a one-time promo code. For example, a 15% code on a single order might be better than the 10% subscription rate if you're only buying once. However, if you plan to reorder regularly, the subscription's recurring 10% discount often provides better long-term savings.

Pro tip: Use one-time promo codes for your first purchase, then switch to subscriptions for ongoing orders to lock in consistent 10% savings without worrying about code expiration.

MET-Rx free shipping codes have varying minimum order thresholds, typically ranging from $55 to $85 depending on which code you're using. The most common thresholds are $59 and $60, which is why your order under $60 likely didn't qualify.

Specific shipping code minimums:

Different free shipping codes have different requirements—some require $55 minimum, others $59, $60, or even $85. The code details should specify the minimum, but many people miss this requirement when copying codes. For example, one code requires orders of $59 or greater, while another requires $60 or more. The subscription program offers free shipping on orders over $85.

Why your code isn't applying:

If your order is $58 and you're using a code that requires $59 minimum, it won't apply—you're just $1 short. The system won't partially apply the code or round down. You need to either add one more item to meet the threshold or use a different code with a lower minimum (like the $55 option if available).

How to find the right code for your order size:

Review the code's specific terms before applying it. If you're ordering under $60, look for codes with $55 minimums or consider using a percentage-off code (like 10-15% off) instead, which typically have lower or no minimum order requirements. Codes with percentage discounts are often more flexible than free shipping codes.

Pro tip: If you're just under a free shipping threshold, add a small item (like a single packet or smaller product) to reach the minimum—it's often cheaper than paying shipping fees.

No, you cannot stack or combine multiple MET-Rx promo codes on a single order. The checkout system only allows one code per transaction, which is standard across most e-commerce retailers.

Why code stacking isn't allowed:

MET-Rx, like most supplement retailers, restricts code combinations to prevent excessive discounting and maintain pricing integrity. Allowing customers to layer a 10% code plus a free shipping code plus a 15% code would significantly cut into margins. This is why the site's subscription policy explicitly states "no additional promotional codes can" be combined.

What happens if you try to apply multiple codes:

When you enter a second code at checkout, it typically replaces the first code rather than stacking both. You'll only receive the discount from whichever code was applied last. Some checkout systems will show an error message stating codes cannot be combined.

How to maximize your discount:

Choose the single code that gives you the best overall savings for your specific order. If you're spending $100, a 20% code ($20 off) beats a free shipping code. If you're spending $50, a 15% code ($7.50 off) might be better than free shipping if your order qualifies. Calculate the actual dollar savings from each available code and apply the one that benefits you most.

Pro tip: Compare your top 2-3 codes by calculating the exact dollar amount you'll save with each, then apply the winner—don't just assume the highest percentage is always best.
