I always go to the companies site, load up my cart, and compare prices. RodentPro, Mice Direct, and Loxahatchee are all consistently cheaper to Michigan. . I've never ordered from Big Cheese for that reason. If you order $100 worth ARS are by far cheaper than anyone. RodentPro's issues were with getting rodents from outside sources when they ran short on their own stock. I haven't heard about any problems since they had to shut down with the bacteria scare. I really don't know why people get so bent out of shape about feces or urine on the rodents anyway. Aren't they in the insides of the rodents anyway?
