How coupon codes work on Arduino
General tip
Redeeming a coupon typically involves applying a code during the checkout process. Arduino’s terms describe the availability of Premium Services and related charges when you purchase through the Arduino online shop or digital store. If a charge is associated with a Premium Service, you’ll be notified of that charge on the Arduino shop and must agree to pay it. The site may require an account for certain functionalities, and eligibility for Premium Services is governed by the terms.
Codes are often tied to specific products, services, or account types
Some services require an activated account to access discounts
You must agree to any stated charges for Premium Services at checkout
03
What coupons cover and common exclusions
General tip
Coupons and discounts usually apply to eligible Arduino products and services purchased through the Arduino online shop or digital store. Exclusions, stacking rules, minimum order values, and new-customer limitations are generally defined by the specific offer. Always review the terms tied to each discount in the promotion details and in the store’s policy pages before applying a code.
