Yes, If the main reason you're looking for a VCC for your PayPal is so you can buy bitcoin, using Bitcoin Debit Cards would be easier and you won't have to go through PayPal either. If you're set on using PayPal however, then go to the Digital Goods sections. There are plenty of sellers there who offer VCC for PayPal/Amazon.
