About King Arthur Baking

King Arthur Baking is an American baking company founded in 1790. It's based in Vermont, where it runs two baking schools and a café in Norwich. The company sells flour, mixes, tools, and appliances online.

For orders, returns, or account issues, contact customer service at (800) 827-6836 or [email protected]. They're open Monday to Friday from 9 a.m. to 7 p.m. ET, and weekends from 9 a.m. to 5 p.m. ET.

The Baker's Hotline is different. It's only for recipe questions, not orders. Call (855) 371-BAKE or email [email protected]. Hours match customer service, but the line closes on major U.S. holidays.

Free returns for damaged or defective items

Free return shipping only applies when an item arrives damaged or stops working. For those cases, reach customer service first by phone, email, or chat before sending anything back.

King Arthur mentions a satisfaction guarantee on its customer service page, but it doesn't spell out the rules for change-of-mind returns. The return window isn't posted, and there's no clear answer on who pays for shipping. Plan to cover return shipping yourself unless customer service tells you otherwise. If you're unsure about an item, ask about return eligibility before you check out.

For an appliance still under the manufacturer's warranty, go straight to the brand. Most manufacturers handle repair or replacement themselves, often with no shipping cost to you.

Take photos of any damage before opening a case. Shoppers on r/KingArthurBaking report faster responses when photos are attached to the first message. Hold onto the original packaging too, in case customer service asks for the item back.

Frequently asked questions about King Arthur Baking

How Baker's Rewards works

Baker's Rewards is King Arthur Baking's free loyalty program. Anyone can join the Basic tier, and members who spend at least $200 a year auto-upgrade to Gold, which is the point where the program starts paying off. Below that mark, points may expire before you collect enough to redeem.

Both tiers earn 1 point per $1 spent, and 100 points turn into a $5 reward. Gold raises the earn rate to 1.25 points per $1, or 1.5 points per $1 once an order hits $150 or more.

A $200 Gold order earns 300 points ($15 in rewards), while the same order at Basic earns 200 points ($10). To hit the higher 1.5x rate, bundle your restocks into a single order over $150.

Gold also comes with three perks Basic doesn't have:

  • A 100-point welcome bonus on upgrade, double the 50 points Basic members get.

  • A doubled birthday bonus, 200 points instead of 100.

  • A once-a-year free standard shipping coupon, issued every January. This coupon is good on orders of $75 or more shipped to the contiguous U.S.

A couple of setup notes apply to either tier. Add your birthday to your profile at least two days before the date so the bonus lands on time. Also check your points expiration on the Rewards Dashboard, since points expire 365 days after your last qualifying purchase.

For shoppers spending $150 to $190 a year, one extra order to clear $200 turns the Basic earn rate into Gold for the rest of the calendar year. Anyone spending under $150 a year is better off staying on Basic and redeeming points within 365 days of their last order so they don't expire.

How to use a King Arthur promo code

Apply your promo code on the cart page before moving to checkout. The field looks the same on desktop and mobile browsers. Here's how to do it:

  1. Add your items to the cart.

  2. Open the cart page.

  3. Find the Enter Coupon Code field, located under the Order Summary tab.

  4. Type in your code and click Apply.

  5. Continue to checkout.

A few rules limit how codes work together. Codes can't be combined with other offers, and Baker's Rewards allows only one reward per transaction. So a sitewide percent-off code, a reward redemption, and the Gold free-shipping coupon can't share one order. The workaround is to spread them across separate orders, like using a percent-off code on one and redeeming a reward on the next.

When a code won't apply, check these four things:

  • It may be new-customer-only. The 20% welcome code works on a first order of $50 or more.

  • It may have expired. Welcome codes usually run out 30 days after they hit your inbox.

  • Your cart may have excluded items. Appliances, gift cards, and Baking School classes are often left out, but each promo lists its own.

  • Your cart may be under the minimum. Each code sets its own spending threshold.
