I would compare eBay and Apmex. Believe it or not, sometimes, your local bullion/coin dealer will have good prices. Compare prices! Of course with silver iShares, you have the benefit of instant liquidity. Also, one doesn't have to worry about burglars coming in the house to steal iShares. Then again, there's nothing like having the physical silver in your possession. No paper trail. Can't be litigated away from you. Can use for bartering if world financial system collapses. I like to diversify into many different types of exposure to silver.
