Where/How do I get the best deal when buying two motorcycles at the same time?

I'm planning to buy two motorcycles (Honda Rebel and Kawasaki Ninja), new, for Christmas. How do I go about getting the best deal? Does it make sense to buy them at the same time? At what place can I get the best deal at in the San Francisco Bay Area?|||Do the bikes have to be a different brand? You will be better off buying them together, as the dealer will be able to write off part of the cost by moving more product, so by selling in volume he will be able to write off some of the cost to you. The Honda CBR RR bikes are very similar to the Ninja, and in my opinion are actually better bikes. Kawasakis are at the bottom of the supersport bike totem pole right now. If you are deadset on these two specific bikes, find a dealer near you that is both Honda and Kawasaki.|||If buying from different places then play one off against the other. State you are looking to purchase either the Honda or the Kawasaki and depending upon which is the best deal is what will make the decision for you. Then you will get the best deal on both.|||It's a BUYERS market, if you can find a combineddealer of Honda and Kawasaki you can get over lapping discounts.|||what you do is give them your maximum price and tell them to work with it if they want to sell the bikes.
