I've ordered from http://www.sal****erfish.com with no problems ...
livestock was well packed with heat pads, and all the critters were
very healthy and active. I would order again with no hesitation. They
ship for free on orders $75+ (with $5 handling fee)

The other online store that I was considering was
http://www.drsfostersmith.com. They ship for free on orders above
$175.
