Really? Perhaps I'm atypical, but PayPal as your payment option always struck me as amateur hour. Not enough to keep me from buying, but it doesn't inspire trust.

If PayPal really enhanced customer trust, I'd expect to see more large retail corporations using it as a payment option.

many people keep money in there and treat it almost as virtual currency. They can just use paypal money to pay, it's secure, etc.

There's a whole class of people who can't get a credit card in the first place, but they can use paypal tied to their bank and move money in.

Paypal is more universal around the world than most other cards. Someone may have a JCB card or a Switch card - my standard merchant account gives me a harder time with those, and charges me a heftier fee, and in some cases I can't take 'overseas'-based cards at all (Solo cards, for example) - but those people in those countries can use PayPal - and they do with me.
