Most shops on Etsy accept payment via PayPal, including payments made by credit or debit card. However, if you don't have a PayPal account, you may still be able to pay for your purchase with a credit or debit card using PayPal's guest checkout service. (There are some limitations to this option, noted below.)

The first step is to find an item you love and want to buy. Click Add to Cart on the listing page to place the item in your cart. Be sure the listing says the shop owner accepts payment by PayPal by checking in the payment section of the listing:

When you're ready to check out, choose PayPal as your payment method. You'll notice the credit card logos next to the PayPal logo because credit card payments can also be processed through PayPal.
Fill in the other order details, such as a note to the shop owner, a coupon code, etc.
To proceed, click the Check out with PayPal button. You'll be taken to a secure page on PayPal. Look for a link below the log-in form reading Don't have a PayPal account? The screenshot below shows where to find this link:
You'll then be prompted to fill in your billing and credit card information. You will be given the option to create a PayPal account, but you can decline that offer and continue your payment.
Once you have completed the information on PayPal, you will return to Etsy Checkout to review and submit your final order. Your payment is not sent until you click the green Submit Order button on Etsy.
Shoppers take note! PayPal may limit the number of times a credit card can be used before requiring that you create a PayPal account. Please contact PayPal's customer support for specific questions about their guest checkout limitations.
You can also pay for your items using direct checkout. Learn more about direct checkout.
