You will be able to pay by credit cardPayPal account or direct bank transfer.

Paying by credit card or PayPal

During the payment process you will be redirected to the official website of PayPal where you can pay using all major credit cards without opening a PayPal account or logging into one. 

To pay by credit card (in most cases) it is not required to open or have a PayPal account. When you get to the PayPal site  you either see the credit card form or a PayPal login screen with a gray button "Pay with Debit or Credit Card". Clicking on this button the payment form comes up and you can fill in your credit card information; your personal information (name, address, phone number) are also asked for invoicing purposes.

After payment you will get a receipt by mail and will be redirected back to this website.  

The payment process is completely secure on this site, financial information will be only asked on the PayPal site and it will not be transferred to this website.

Paying by direct bank transfer

During the payment process you will see the account and bank information. This information is also available from a link in the footer after login.

Eventual problems on the PayPal site

PayPal is advertising that it is not necessary to have a PayPal account for credit card payments. In most cases this is true, however, it might happen that you can not pay with credit card without using your PayPal account or opening a new one. PayPal has fraud prevention measures in effect for all transactions and therefore, in some cases, PayPal might prevent a customer from using this option. This might happen based on a number of factors:

  • Incorrect email address: your email address might be incorrect, or PayPal was unable to verify it.
  • The billing address you entered on the website is different from the address on your credit card statement. 
  • You have cookies of PayPal on your computer from a previous transaction that have not expired yet.  
  • Your location is not supported: in certain countries this option is not available, or the number of possible use is limited.
  • You have used the same credit card a few times with PayPal (3-4 times).

What can you do to still pay with PayPal without opening or logging into a PayPal account? Try one of the options below:

  • Make sure that you use a valid email address. Try to delete the email address in the email address field and refresh the page;
  • Make sure that the billing address that you enter for your order is the same as the address assigned to your credit card account. PayPal compares the street number and zip code entered by you with information maintained by the card issuer.
    There might be more than one addresses for you in the website. After login -> My account, left menu:
    • Customer info address: this is the address you entered on the registration form.
    • Addresses: if you added a new address as billing address during the payment, then you will see it here. Both addresses can be changed. 
  • If you do not see the credit card form or the Pay by debit or credit card link: Delete the  web browser's cookies, temp files and history, then close the web browser, reopen it and try again. (Deleting the cookies might be also useful, if you have changed some data, like your phone number or address.) Or open a New Private Window (in case you use Firefox) or a New Incognito Window (for Chrome) using the menu on the top right and try again;
  • If you are forced to login or open a PayPal account: if you can't/don't want to do that, use a different credit card. 

If these ideas do not help you, you might consider paying by direct bank transfer. We are very sorry for the inconvenience, these features of PayPal are not in our control.
