I have PayPal set up as my backup funding source at iTunes, but I usually run a positive balance there. I currently have about $20 in my iTunes account. Lately, however (in the past month), I'm noticing roughly half of my iTunes purchases are being charged right to my PayPal account rather than taking from my iTunes balance. Anyone know why this might be? No one has "hacked" my account. The purchases are legit, but I don't understand the re-directing of the funding source.
