Peter Stone Promo Codes & Coupons June 2026

Peter Stone typically allows only one promo code per order. Attempting to apply a second code at checkout will usually trigger an error such as "Invalid promo code" or "Only one code allowed."

This comes up most often when shoppers try to combine a percentage-off code with a free shipping code on peterstone.com. The system will reject the second entry, so you'll want to choose the single best code before completing your purchase.

To get the most out of your discount:

1. Test each code individually in the promo code field at checkout.
2. Compare the savings from each and select the one with the highest value.
3. Note that free shipping thresholds (such as orders over $70) may apply automatically without needing a separate code.

Pro tip: Check SimplyCodes for the latest verified Peter Stone codes before checkout so you can quickly compare and apply the best available offer.

Most Peter Stone promo codes do not stack with items that are already on sale or marked down. If you try to apply a code to a sale item, you may see an error such as "Promo not applicable to discounted products."

This is a common limitation across Peter Stone's checkout — percentage-off codes like 20% off tend to work best on full-price items, including their custom and sterling silver designs, rather than on pieces already reduced during a flash sale or clearance event.

To avoid checkout frustration:

1. Add the item to your cart and enter your promo code.
2. Watch for any red error banner indicating the code isn't valid for that item.
3. If the code doesn't apply, try switching to a full-price item to use the discount.

Pro tip: On SimplyCodes, look for codes labeled "sitewide" or "full-price items" to find the ones most likely to work on non-sale Peter Stone jewelry.

Many Peter Stone promo codes do apply to custom and personalized jewelry orders, particularly sitewide codes. Shoppers have successfully used percentage-off codes on bespoke sterling silver pieces, including personalized Celtic knot designs and custom engravings.

That said, a few restrictions can still apply:

• Minimum order thresholds (such as $70 or more) may be required for the code to activate.
• Free shipping perks may only kick in after the discount is applied and the order total still meets the minimum.
• Codes can expire quickly, so it's worth verifying before you start building your custom piece.

To apply a code to a custom order:

1. Use Peter Stone's design or builder tool to configure your personalized piece.
2. Add it to your cart before entering any promo code.
3. Input the code at checkout and confirm the discount is reflected in your order total before finalizing.

Pro tip: Build your custom piece first, then visit SimplyCodes to grab the highest available Peter Stone discount code before completing checkout.

The Peter Stone refer-a-friend program is primarily intended for the referred friend's first purchase. The new customer receives a discount (such as 20% off) on their initial order, while the person who referred them may receive store credit after that purchase is completed.

A few things to keep in mind:

• The referral discount is tied to new customer accounts, so it won't apply if the referred person already has an existing account.
• The referrer's credit is typically issued after the friend completes their qualifying purchase.
• Referral credits and codes are generally not stackable with other active promo codes.

To redeem a referral offer:

1. Obtain a unique referral link from a current Peter Stone customer.
2. Sign up as a new user and shop using that link.
3. Apply the referral discount at checkout — credit may also be automatically applied or sent via email.

Pro tip: Even if you've used a referral code, check SimplyCodes for any additional Peter Stone promo codes that might apply to your next full-price order once the referral credit has been used.
