I want to buy some products on Vova website. I can see that PayPal is accepted by them. Please say if I get 180 days buyer protection if I pay there using PayPal. Also mention how I can verify that a merchant accepting payments via PayPal qualifies for 180 days buyer protection.
That depends on MANY factors all listed in Paypals buyer protection policy for you to read so you can risk assess your transactions. Legal (bottom right of Paypals pages) > user agreement > buyer protection.
Advice is voluntary. Kudos / Solution appreciated.
