Reading today's numbers
Only one vendor currently lists Dairy Cow Isopod, so today's range ($0.24–$1.18) reflects that vendor's own listings rather than a cross-vendor comparison. A spread that wide usually reflects real differences between the listings — group size is the usual driver, since larger cultures tend to work out cheaper per isopod, and some listings mix sizes or include breeding adults. When judging a price, the median ($0.62) is the better anchor than the low: the cheapest listing can be a large-culture price. If a quote is well above the median, check the vendor table above to see what group size you're comparing against. Note that 4 of 7 tracked listings are in stock right now; today's stats come from the in-stock ones.
