E-checks are not an instant payment method. Usually, an e-check clears within 3 to 5 business days. When your check clears, PayPal sends an automatic notification to us and only then the delivery is made.
Log into your PayPal account and look-up the transaction to find out an estimated clearing date for your e-check.
