I tried using the Paypal to pay an item but this message came up,
Many debit cards have daily limits on spending or on where you are buying from. This is to protect you from a thief getting your card information and cleaning out you bank account. Contact your bank and find out what your daily limit is and if they have limits on internet purchases in place.
many other people have got the same problem when make paypal payment. paypal usually show the error message like” unfortunately your payment was declined by your card issuer” and they find the way to fix it there:
Source: Paypal error: Unfortunately your payment was declined by your card issuer
