IMPORTANT NOTICE:
 

We improved our system! This will affect you positively in the following ways:
  • Now your credit card transaction will take 2-3 minutes and you will receive an email confirmation immediately.
  • Your account will be updated within 5-7 minutes.
  • If you are a new customer, the initial approval process may take up to one business day. After that your transactions will take the same 2-3 minutes.
  • We protect you from accidental duplicate transactions! It means that the system allows only one transaction a day for one pair of credit card and amount (order total). If you want to make more than one transaction a day, please choose another transaction amount or use another credit card.
  • All credit card transactions are now automatic. Please fill out your billing address carefully. It must be the same as on your credit card issuer account.
