Depends on what you use Paypal for. I recently learned of what seems to be an intriguing alternative for paying people online w/o a Paypal account or a regular debit or credit card: American Express gift cards. They cost ~$5 ea, and you can put up to $200 on them. Available at Shaw's in Porter Sq. You can pay cash and basically have an anonymous disposable credit card. Or so theory goes. Usable anywhere American Express is accepted.
