I have a D3 on order from crutchfield and im sure as a bunch of you know that if you ordered 2 other pioneer accessories you savd an additional 15%.. so i ordered the ipod cord and the sirius radio adapter. however i have the same sirius adapter already just ordered it to get the deal.. the question is is if i return the one i get after my order has been shipped and ive gotten everything, will they just return me the $99.00 for it and not change the price on the whole order??
