Hi Sue, I only joined Paypal a couple months back, i have been using it on Ebay as well, but not all sellers on Ebay in Australia will accept it, but a few do.
I dislike credit cards myself, don't like spending money that i haven't saved already myself, that's the good thing about Paypal it just deducts money from my own bank account and doesn't cost a mint to run, like some credit cards do.
all the best,
Brian
