Another good place for well priced drum heads, or any percussion item pretty much under the sun, is here.
"www.lonestarpercussion.com"
Since I don't know what sizes or types you bought, I won't assume a better or worse price. It's always good to have two or three powerful store choices when buying musical equipment. One of the good things about regional percussion stores, such as yours and this one, is that they are run by percussionists specifically, and can answer your questions. Also, in my experience, Lone Star Percussion shipped more quickly than Sam Ash, but Sam Ash is a good place, and I haven't bought the same items from both or compared prices intensely.
