There are probably some here who would post nonsence in order to led others to believe that Ebay is a terrible place to shop just to direct sales back to retail stores. But, no doubt there are scammers on Ebay, and retail stores have there own sucker game. I have heard some real bullcrap come out of sales peoples mouth, just to sell you equipment. Its always buyer beware no matter where you shop for electronics...cars...almost anything expensive.
1. Make sure your PayPal account has a different password than the email account that receives notifications from PayPal.
2. Make sure your Ebay account has a different password than the email account that receives notifications from Ebay.
3. Make sure your Ebay and PayPal passwords are not the same.
Doing this will make it easier to survive in the online world.
