PayPal requires a shipping address before you can pay me (even though I don’t need it if you’re only ordering patterns!) If you don’t have a shipping address listed in either your PlanetJune account or your PayPal account, please add your shipping address to one or the other and then try to check out again.
If you don’t have a PayPal account, please make sure your name and billing address are spelled exactly the same way as they appear on your credit card statement, otherwise your credit card company won’t let PayPal proceed with your transaction.
If you do have a PayPal account but you’ve recently changed some of the details for your linked credit/debit card (e.g. you received a new card with a new expiry date, or moved house and so changed your billing address), make sure you update your card details in your PayPal account.
If you have a PayPal account and your card details are up to date and you’ve entered your shipping address but you’re still experiencing difficulty in paying, it may be a temporary glitch at PayPal’s end. I suggest you wait a few minutes and try again, and then, if it still doesn’t work, contact PayPal customer support for assistance (and copy and paste the error message into your email so they can help pinpoint your problem).
