Hmm. Your experience is different from mine. I was ripped off by an EBay seller who advertised Adobe software as full version, unregistered and showed a photo of the box, but delivered CD-R's with handwritten labels. As soon as I chose "Product not as described" at Paypal, the web for said that "PayPal does not get involved, take it up with the seller", and then locked me out for any other complaint on that transaction.
Here is their written policy at
https://www.paypal.com/row/cgi-bin/webscr?cmd=p/gen/ua/policy_buyer_complaint
"The Buyer Complaint Policy does not apply to claims that a product was received but is not as described by the seller."
Now PayPal does have some eBay buyer protection insurance, and it does cover "goods that are significantly not as described" but it is highly restrictive in which transactions qualify, so although the auction may display a PayPal protection logo, essentially the only sellers it covers are the honest ones :
" 1. The seller's eBay feedback rating is at least 50;
2. At least 98% of the seller's eBay feedback is positive. The percentage calculation for this purpose includes feedback from repeat users, and therefore may be higher than the unique positive feedback percentage displayed on eBay;
3. The seller is a member of PayPal in one of the following countries: U.S. Canada Germany U.K.
4. The seller has a Verified Premier or Business PayPal account;
5. The seller's PayPal account is in good standing."
Remember: Both eBay and PayPal are in the business of collecting commissions, which they do
whether the sale is good or bad. They are not in the business of protecting you from frauds, and their efforts to do so IMO are the minimum to maintain a positive public perception of their services.
