Never buy from them through Ebay unless you are using the bonus bucks or something. Otherwise go through their website and it will be a little cheaper.
I found their website to be about the same price. For 10 ounces of silver the website price is $176 and ebay is $178. The biggest difference being that you have to pay by check or wire transfer in order to get that cheaper price. I rather pay the extra 2 bucks and not have to provide my bank account information. It also takes a week to have check or transfer clear before they ship. On ebay they ship next day.
I'm going to get my girlfriend to buy me another 10 oz deal with her address. I'll pay her of course. It's like buying when spot is at $15.16. Update: They just pulled the 10oz deal. Bummer. Maybe they'll do the 10oz bar next like they have in the past.
