He's had 1 positive feedback on ebay recently, that was from a purchase from somebody in December; must have been the last guy to get his order, or more than likely he's a friend of Defranks and it's all a set up.  Defrank's gone from a 100% seller rating in December to a 90% today.

On facebook, he has both a business page, as well as his person page (https://www.facebook.com/mark.defrank.71?fref=ts), on which he appears to have been active on March 5 posting a photo of his Primanti Bros sandwich..

No idea if it's current or not, but he also has a physical business address listed on his website as 702 Duck Hollow Road Ext, Uniontown, PA. So if we got any curious yinzers down in those parts, may be worth taking a ride over there and seeing what the deal is...

Very fishy (pun intended) that he'd seemingly just fall off the face of the earth.
