Depends on the bumper style desired.
But likely..the Dealer will be your best bet as the shipping for such an Item can easily run $100.
SO even if you find it $50 Cheaper then the dealer somewhere (Lets say $150) and then you ship it for $100....Its now a $250 Bumper.
If the Dealer Sells it for $200...then there is no shipping..local pickup..and $50 Cheaper.
Definately something to consider on this particular item.
And the MSP/MP3 Bumper has a list price of $247 @ the Dealer For reference IIRC.
