I haven't bought any yet but have been looking into it. Shipping is the expensive part. I want some Red Cherry Shrimp and can't find any locally. I did find some at azgardens.com for $4.59 each. They are in Arizona and I'm in NC. I think the shipping for 2nd day is about $15 - $25. Overnight is about $35 or $65. You almost have to order 10 or more to make it worth while, depending on where you are in relation to the shipper. A lot of them guarantee them to arrive alive or they will replace them but you still have to pay freight on the replacements too.
