Stuff like this always makes me wary of buying on eBay. I never brought anything on eBay yet but I've been thinking about it. I'm paranoid at buying stuff over the internet and the only places I buy things from are
newegg ,
Video Game Depot, and
Eastbay . Its a rarity that I buy from them, at that. I only order something online if it isnt in the stores.
But I still have a small intrest in eBay... thinks like this arent making my intrest any greater.
But I hope you sort your problems out ASAP. Perhaps even beat up the person who stole the necklace, if anyone did.
