Heck, anything you don't use at those prices,you could easily re-sell at Ham Radio 'Hamfests' in your area.
Maybe not at the Radio Shack full price, but at better than whay you're paying.
I highly recommend Googleing 'Hamfest' in your city, and finding ones close by to buy or sell electronic components.
The clubs in the city near where I live have one Hamfest in the spring, and another one in the fall. Every vendor and every buyer out for electronic parts deals.
