Very true about CC companies. But if you have ever tried to actually get a refund with a CC company, it takes a lot of work, phone calls, waiting for them to contact the other party for their side of the story, etc. If it's outright fraud they do act quickly... cancelling your card and you wait a week for another one.You're right, most folks do have good experiences with PayPal, as do I (I mostly use it for ebay where sellers often can't take direct CC payments). The thing is that because PayPal is the intermediary, buyers are paying PayPal, so it's up to PayPal to decide if they've met the obligation for the transaction, which is pretty much like an escrow. However, once they release the payment to the seller (which takes place after they are satisfied that the exchange has occurred), they are usually hands off, because there isn't much they can do from that point. If you don't receive your goods/services at all, that's an easy one for PayPal. If you get a tiny $8 toolbox instead of an enormous tool rack, that may be more complicated.
Credit card companies, on the other hand, have many more tools at their disposal and are in fact motivated by their legal liability for the payment. If the CC company does ever take a loss (rare), that cost is already built into the service (on the seller's end). If you are unlucky enough to have to file a complaint about a CC transaction, typically you'll notice that your account gets credited immediately (while the company investigates it).
I've found Paypal stands behind the purchase even if they've paid the seller. But I think they don't pay sellers right away UNLESS it's someone they've approved over time. They will eat it if they have to. They offered me "Paypal Protection" years ago. Maybe it's because I have used them for probably 20 years, they treat me differently? I really don't know, and I know that minimal users of PP have some bad experiences.
But for me.... anything I don't want the other end of a purchase to have my CC #....... I use Paypal. It's been bulletproof.
