You can get the same flies at Cumberland Transit, Fly South in Nashville and Joel on the Caney. They can also help hands on with any product needs.
The internet is a great tool for getting stuff cheaper and I have used it as well but in my opinion it is worth the few cents difference in price to get to talk to someone in person with knowledge plus advice for where I am planning on fishing.
