I order all my fish from saltwaterfish.com. Their customer service is non-existant, but their livestock is always good and you certainly cannot beat their prices.
They also require a minimum purchase of $79. If you can find someone in your area willing to split the order I'm sure you could come up with $40 order with a goby, some cleaning crew, maybe a shrimp or something.
If you don't know anyone in your area that does SW
look here in the forum for your area and post that you are looking to place and split a livestock order.
