Why did I not learn the first time?!

  1. God I'm feeling like such an idiot at the moment! Two weeks ago I brought a Fendi B bag from eBay that turned out to be fake and now I think I've gone and done it again! I brought a Stam in metallic gold that was apparently brought from Saks but I stupidly didn't check if Marc Jacobs even made gold stams! Does anyone know if they do?? And if they don't as I only paid for it via paypal three days ago is there anyway I can halt the process so I can get my money back? Thank you!
