sorry for the newbie questions on PPC. 1. When voucher expires and I still have voucher credit in the account does it go past the expiration date OR do they start using my money? (example: i have $100 but expires in 2 weeks but I only use $50 so far) 2. When voucher expires can I use another voucher in the same account? or do I need to make a new acct with new voucher?
