Azureus are great frogs - you'll enjoy them.
We don't have very many frog breeders in Texas, so I usually have to buy from folks up north. They ship them overnight in small deli cups with damp moss secured in a square Styrofoam container with a cold gel pack. I pick 'em up at FedEx, so it usually ends up being a 24hr trip for them. I've heard of frogs surviving more than a week after being lost in the mail. They're a little more hardy than they're made out to be.
They can go several days without food, so be stingy with the fruitflies until you get 'em home. Too many flies can stress them out. Add a piece of fruit like banana or half a grape to their container to keep the flies in one place. I keep fruit in all my tanks.
