PayPal Provides the ability for consumers and businesses to send and receive money online with the use of an email address and credit card number or bank account. Trying to exceed the limits freezes your account and ties money up for weeks.
Email support can be slow on a personal acct.
Chargebacks - User Agreement precludes chargebacks. Your credit card company cannot be asked to stop payment on a charge you authorized through PayPal. Last minute holiday shoppers risk not getting their gifts in a timely fashion due to high volume shopping.
