Alza Days - Summer Diesel Additives

Alza Days

  • The campaign runs from June August 10 to August 24, 2026 (“Campaign”).
  • The list of products currently available in the Campaign (“Products”) can be found on this website below.
  • A Product is considered purchased at a discounted price as part of the Campaign only once the order has been confirmed by Alza and the payment has been completed by the customer. Simply placing the Product in the cart does not constitute a purchase. If the Buyer selects cash-on-delivery payment, submitting the order to Alza within the Campaign period is sufficient, but the discount will only be valid upon successful payment upon delivery.
  • Alza reserves the right to limit the number of Products a single buyer may purchase during the Campaign for certain items. Should such purchase limits apply, Alza's system will automatically prevent buyers from adding more Products to their cart than the permitted purchase quantity for the duration of the Campaign.
  • Available stock of select Products will be allocated among consumers in the Czech Republic, Slovakia, Austria, Hungary, and other countries served by Alza.
  • Discounts on Products are valid only during the Campaign period or while supplies last. Alza reserves the right to change the selection of discounted Products at any time during the Campaign.
  • The general terms and conditions of the Campaign can be found here.
