Silver Eagles in stock at some dealers - $5 premiums

This internet coin dealer has 2013 silver eagles back in stock.  The premium to current metal value is about $5 per coin.  The US Mint charges authorized partners a $2 per coin commission.  The dealer's up-charge is therefore currently about $3, which is about $2 more than early this year before the mid-April price smack down.

Another internet coin dealer has silver eagles available at about the same premium.  Although it is not clear which year of silver eagle they are offering.  And a third dealer has orders for silver eagles on a 2-3 week delay.

The buy price at this dealer is $26.58 which is $0.65 more than the current spot ask price as reported by this same dealer.  Presumably this dealer can purchase silver eagles from the US Mint for $2.00 over spot, so why are they offering $0.65 more?
