floridapets.com does....it's like 7.00 a bag. i've ordered from them several times. just be aware that from floridapets.com you will get a bag of copepods, isopods, amphipods and some mud/algae with it. it's not a clean mix of copepods like oceanpods.com sells.
i also think that ipsf.com also sells pods kits but i have never ordered from them.
