CannonKeys Promo Codes & Coupons September 2025

Yes, CannonKeys promo codes often have specific restrictions based on product type, collection, or minimum order value. For example, some codes only apply to orders over a certain dollar amount, while others are limited to certain items like keycap sets or switches.

Many promo codes are sitewide, but others are tied to specific products or require you to buy a minimum quantity. Clearance items and heavily discounted products are frequently excluded from additional promo code use. Always check the details listed with each code, as restrictions are usually stated clearly at checkout or in the promo code description.

Pro tip: Before shopping, review the promo code’s terms and try adding eligible items to your cart to see if the discount applies—this helps avoid surprises at checkout.

No, CannonKeys does not allow you to combine multiple promo codes or stack codes with other ongoing sales or discounts. Only one code can be applied per order, and sitewide sales or clearance discounts typically cannot be combined with additional promo codes.

If you try to enter more than one code, the system will usually only apply the most recent one, removing any previously entered code. This is a common restriction in the online mechanical keyboard community, especially for limited-edition or high-demand products.

Pro tip: Compare the value of available codes and sales before checkout—sometimes the automatic sale price is better than a promo code, so choose the option that gives you the biggest savings.

If your CannonKeys promo code isn’t working, it’s usually due to one of these reasons: the code is expired, doesn’t meet minimum purchase requirements, is restricted to certain products, or has already been used. You might see error messages like “Code not valid for items in your cart” or “Promo code expired.”

Common scenarios include:

• Trying to use a code on clearance or already discounted items
• Not meeting the minimum spend
• Entering the code incorrectly (codes are case-sensitive)
• Using a single-use or exclusive code that’s already been redeemed

Step-by-step solution:

1. Double-check the code for typos and case sensitivity.
2. Review the code’s terms for product or order restrictions.
3. Remove ineligible items from your cart.
4. Try a different, currently active code if available.

Pro tip: Use community-verified codes from reputable sources and check recent user feedback to ensure the code is still active and valid for your order.

CannonKeys does not allow stacking of promo codes—only one discount code can be used per order. If you have a code for a percentage off and another for free shipping, you’ll need to choose which one to apply, as the checkout system only accepts a single code at a time.

Additionally, free shipping offers are typically either automatic (applied at a certain cart value) or require their own code, which cannot be combined with other discounts. This is a standard practice to prevent excessive discounting on high-demand products.

Pro tip: If you’re close to a free shipping threshold, add a small accessory to your cart to qualify for automatic free shipping and use your promo code for the best overall value.

If your CannonKeys discount isn’t reflected after clicking "Apply," first check for an error message—common ones include “Code not valid for items in your cart” or “Minimum order not met.” This usually means your cart doesn’t meet the code’s requirements or the code is expired.

Here’s what to do:

1. Review the promo code’s terms for product or order restrictions.
2. Make sure your cart meets any minimum spend or item requirements.
3. Remove ineligible items or try a different code.
4. Refresh the page or clear your browser cache and try again.
5. If the issue persists, contact CannonKeys customer support with your cart details and the code you’re trying to use.

Pro tip: Always copy and paste codes directly from trusted sources to avoid typos, and double-check your cart for any excluded items before applying a code.
