1. How to pay amazon store debit card with discover rewards on GE money?
Know the basics. Debit cards look just like credit cards and can usually conduct transactions in exactly the same manner, but they provide funds in very different ways.
Look for the card that suits you best. Banks and credit unions want every customer/member to have a debit card, because it is more convenient and lucrative (through fees) for them.
Keep tabs on your available funds. With a credit card, you can spend up to your credit limit and worry about how to pay for it all when your statement comes due.
Consider when not to use your debit card. As mentioned earlier, you can use a debit card anywhere you can use a credit card.
2. Is safe to buy from using a Paypal debit card on amazon?
It should be safe on a secure site, but it is always best to use a credit card. If there are any fraudulent charges you can dispute them and get them reversed. With a debit card you are on your own, and once they have your information they can wipe out your checking account. I had $2500 in fraudulent credit card charges reversed in Jamaica a couple years ago. I would have been in big trouble if they got my debit card info.
