umd, good point. But often people start with some idea, like OP's Rival/Red/6700 combo, and they start looking at the price on a specific package, and prices for alternatives. Suppose somebody offered to throw in a Red FD. Looks good at first glance, right? It can happen that a package with "something better", according to list price, which really isn't necessarily better, is offered.

OP is looking at a certain package. But are you sure he won't then look at some alternative options? A lot of people would, especially people who are looking at odd gruppo combos--they're not looking for std packages.
