Horizon Hobby has been mentioned by almost every local hobby store keepers. You can search the parts on Horizon, and ask your local store to special order for you. Every store will be happy to do it for you without charging a lot fee over the normal price.
Besides, these are discount online stores that I’ve bought from:
HobbyKing has almost everything you can image, and everything are cheap. When ordering from HobbyKing, be aware the delivery time may be very long (two weeks or more). And the shipping cost is sensitive to the weight of the package, thus ordering big items may not be as cheap as it appears after adding the shipping cost. They have a USA warehouse, if an item is shipped from there sure it will be delivered quicker.
