I think you were just being impatient, but hey, that's me
Seriously, though, I've been on both ends of the shipping fish deal. There's no money, and a lot of hassle in it for the seller. The seller can't get a refund on the shipping charges, so if something goes wrong, you basically have to swallow that cost.
Uncommon fish can be hard to come by, especially when everyone wants them, or they're in fashion. You either need to be really patient, or have a ton of cash.
