6. Withdrawing Money.
6.2 Withdrawal Limits. Depending on the degree to which you have Verified your Account, we may limit the amount you may withdraw to $500.00 USD per month. You can view your withdrawal limit, if any, by logging into your Account and clicking on the View Limits link on the Account Overview page. In addition, we may delay withdrawals of large sums of money while we perform a risk review.

Review your activity. They could be referring to the past 30 days, rather than the calendar month. Also review what sort of account you have with PayPal, and the fees for that type of account.

Thanks hun
