Hey Vanessa,
Your purchase came through as an echeck. Check the credit card you have on file with Paypal, it probably expired this month and so your default payment method went to an echeck from the bank account you have on file rather than an instant transfer or payment. We always get a rash of echecks at the beginning/end of each month as those cards expire.
As paypal instructs us to do, we hold the purchase until the funds clear from your bank account into our paypal account. Takes 3-4 business days to clear usually.
HTH!
Robin
