Occasionally the large retailers have some pritty good deals/rebates, the best (reliable) deals to be had are still going to be online. Large online retailers (ie newegg) have the best base prices and you don't have to pay any tax on them as all sales taxes are at the state level and out of state mechandise can't be taxed.
Best bet, in my opinion, would be to have some one near where you are staying order the parts you want and give them to you.
Sometimes you can find great deals at computer fairs, but alot of the stuff at those fairs is of questionable origin, if that bothers you.
