They deliver anywhere in the US. I just got a 3 month supply of Frontline for $20 or so. Ask for Lizz if you call the 1-800 #. (P.S. You get better deals if you call or email the reps.) If you would like an email address for my friend/sales rep. that I work with, PM me. I am more than happy to help. They sell tons of pet supplies at great prices. I have saved tons.
