You don't need to swap out your handlebars, your shop needs to do this!!

I'm appalled that you have dropped, what, $4K on a bike and your shop won't get your bars right. When I bought a pricey bike from my LBS the owner told be straight-up that he would swap out the stem or bars if I needed it --gratis. It's all part of the getting things right. Compared to the cost of your bike, handlebars, especially alloy ones, we're talking peanuts here.

Also, I did swap out the saddle for a more expensive one before taking it out of the shop. He credited me full retail for the cost of the saddle before charging me for the pricier one.

Please, please go back to your LBS and have them swap out the handlebars. If you switch to alloy from carbon, ask for a store credit for the difference. There is no reason you should be worrying about selling the bars that came on your bike and buying a new set. Let your LBS show you what customer service is all about.
