I placed an order for five filters, and the shipping was only about $9 IIRC. Also, I received my order in about a week too. The only glitch I has is that I never received the email stating that my filters had shipped. I gave them a buzz and he said that there server has been giving them some grief in the automated mail generator department. Other than that, great service, fast shipping, and quality filters at a pretty fine price.
I'll definitely use them again.
