SiteOne Promo Codes & Coupons February 2026

NEW2ONLINE gives 10% off your first digital order up to $500, but it's exclusive to new customers activating online access. Existing accounts will trigger "invalid code" errors since it's a one-time use per account.

SiteOne's checkout has a dedicated "Promo Code" field after adding items to cart. To apply a code:

1. Enter the code in uppercase letters
2. Click the apply button
3. If valid, the discount will apply instantly to eligible items

If you have a prior login, you'll likely see "code invalid" because NEW2ONLINE requires a fresh account setup via siteone.ca/en/getstarted or siteone.com/en/online. To use this code:

1. Log out, clear cookies, and create a new account
2. Activate online access with NEW2ONLINE at checkout
3. Remember the $500 maximum order value for savings
4. Note that agency products are excluded
5. Valid for online orders only, with no code stacking

Pro tip: Test in incognito mode before full checkout to confirm new-customer status without account history.

"Promo code invalid" means the code is expired, not active yet, product-ineligible, or account-restricted. "Code already used" indicates one-time or per-account limits have been reached.

SiteOne coupons like 10% off $500+ new orders often fail on repeat use or non-qualifying carts. To fix these issues:

1. Check code status on siteone.com/en/promotions
2. Ensure you meet minimum order requirements (e.g., $500 for some promotions)
3. Try logging out and back in, or use a new browser
4. Contact customer support for possible code reactivations

First-purchase codes (like 10% off) are strictly one-time use, while sitewide 5-7% discounts allow broader use but typically exclude bid projects. Many promotions run seasonally, such as September-October or during Early Order Programs.

Pro tip: Copy fresh codes from SiteOne newsletters—email promotions often bypass "already used" errors for single-use perks.

No, SiteOne doesn't allow stacking promo codes. You can use only one code per checkout. The 10% first-order discount is limited to new customers up to $500, while sitewide discounts of 5-10% typically require minimum purchases like $500 on select items.

Attempts to combine codes will result in "invalid" errors. SiteOne's policy prioritizes one discount maximum per order, with no combinations allowed with loyalty or seasonal promotions. The 10% first-order discount excludes agency items and is one-time use only. Larger savings often come with minimum purchase requirements.

Check siteone.com/en/promotions for currently active promotional periods.

Pro tip: Pick the highest-value code first (e.g., 10% on $500+) and apply loyalty benefits via your account dashboard separately.

Online coupons like NEW2ONLINE are digital-only for new accounts, while in-store promotions (such as 15-20% mix/match) apply at branches but not on siteone.com due to separate systems.

Online codes may show as "invalid" because they exclude bid projects or require branch verification. In-store promotions often work for Pro-Plus events but don't carry over to online purchases.

To activate account-specific incentives:

1. Log in at siteone.com/en/online
2. Verify your contractor/Pro status in your account
3. Eligible incentives will either auto-apply or require contacting support

Online promotions typically limit to $500 for first orders, while in-branch promotions often run seasonally (like September-October).

Pro tip: Screenshot in-store receipts and upload them to your account for potential online credit matching.

Contractor codes (such as Pro-Trade or Pro-Plus) require verified Pro account status and often exclude online bid projects or select items. You'll commonly see an "invalid" error if your account isn't properly linked or if you haven't met minimum requirements like $500+.

To use contractor discount codes:

1. Log in and confirm your Pro status is active
2. Enter the code in the checkout field
3. Ensure you meet minimum purchase requirements and aren't buying excluded products

These promotions are typically valid both online and in-branch during specific periods (like September 15-October 15), but some products may be location-specific and agency products are usually excluded.

Pro tip: Use the Pro-Plus app to pre-verify codes before adding items to your cart—this saves you from checkout rejections.

No stacking is allowed. Seasonal promotions (such as 15-20% off 4+ items during September-October) are one-code only and override loyalty auto-discounts. Loyalty discounts apply via your Pro account but cannot be combined with other promotional codes.

Attempting to combine codes will result in "invalid" errors. Loyalty benefits (like newsletter exclusives) are account-based and separate from events like SaveStrong or Early Order Programs. These promotions typically exclude bid projects and availability varies by location and time period.

Check siteone.com/en/promotions for current offers and details.

Pro tip: Log in early—loyalty discounts often auto-apply at their strongest rate if no seasonal code is entered.

Most SiteOne promo codes exclude special order, bid project, or delivery-only items. Standard sitewide discounts (5-10%) work on stock items, but you should verify terms as "some products not available" is a common limitation.

Users often encounter "invalid" errors when trying to apply codes to special orders. SiteOne policies typically flag exclusions for agency/quasi-agency products or non-stock items. Promotions usually apply to in-stock merchandise like mix/match sales, while delivery-specific promotions are rare.

Most promotional periods run seasonally, such as September-October, and are valid both online and in-branch.

Pro tip: Build your cart with in-stock items first, then place special orders separately to maximize your code savings.
