When you are on paypal and looking to pay for a domain via paypal, just make sure your payment option is set to your credit card. Paypal defaults your checking account (those cheap a$$e$--paypal doesn't want to pay the 3.5% to a credit card company for the transaction), so you need to go in and manually switch the funding source to your credit card. You will have to go through one prompt that comees up ("are you sure you want to change funding sources...."), hit yes, pay, and you are homefree.
