Amazon and Barnes & Noble offer free shipping on orders over $25; Powell's offers free shipping on orders over $50. Borders offers free shipping if you sign up for some program that will eventually charge your credit card. Borders.com is the clearest loser in all this. Powell's beats out Amazon by 7 cents, and I like that they are local. On the other hand, three of those books would be used from Powell's instead of new from Amazon. (On the gripping hand, one of those would be hardcover from Powell's instead of paperback, and all the rest would be "trade paper" which according to Wikipedia is considered slightly better than paperback.)
So Powell's it is.
