I bought a Gold Coin from a person posing as an American citizan residing in California, via the iOffer website. I paid for the coin with my Paypal account.
The *** sent me a mold smelling black leather belt after two weeks of ignored emails. I complained to iOffer which never even responded to my complaint! At least eBay has set policies which have teeth and they will work with their clients to resolve any and all issues.
Do yourself a favor, avoid iOffer at all costs and just stick to eBay instead! Ebay is king for a reason ; ) Yeah!
