your shipping from PA right? well Priority Mail Large Flat Rate Box gets to me in 2-3 days tops, and i have not lost any fish sent to me this way, Main thing is adding oxygen tablets and if you have them a 72 hour heating pad, Have to be at the post office before mail leaves the day you ship it, I've always talked with the post office to make sure what time i have to be there, to make sure it gets out the same day... sometimes if people have it they add a stress reducing additive to help the fish with the trip... A lfs will more then likely help you out... I know mine does out here... If possible see if you can get them in one box if not 2 boxes are fine.... With one box id say the price would be about 15 for shipping, plus the fish price...
So single box = around $35-$40
and two boxes would be about $50-$55
Also double bag, and maybe triple on the catfish!
