Oh, that being said - it also depends on the merchant - some will insist on you having a credit card linked to your account, so check out their payment methods.
Yes, and it's great! I love not having to wait 3 or 4 days to use money that is paid to PayPal, and you can even sign up for a cash back rewards program!
No...you just need a bank account. Having a credit card linked to your account makes purchases online much quicker, but it's not a necessity.
I think you do, because when my aunty made hers she had to put one in, and it's still pending because she does not have one.
