Where is the best place to find lop-eared bunnies for thats really cheap?

You should find a local shelter here: www.rabbit.org. I am suggesting a shelter because in general, the majority of pet stores have bunnies who are poorly taken care of, and many are unsure of the gender. (My friend got a pair of bunnies once that were supposedly both females, but then one got pregnant. :p )The Web site is very trustworthy and gives the BEST instructions and tips on how to take care of a pet bunny. I strongly recommend you read through the Care and Behavior pages. You should always make sure your pets are spayed and/or neutered.
