It depends on the shipper and what service you use. Express service to me (in Iowa) from my shipper (in Colorado) is around $45 - that includes the import fee and handling of the fish. That is also on top of the $5 shipping fee you pay the seller on AB, and the original price of the fish. It's not a cheap way to get fish, but if you want something unique or for breeding, it's the best way to go. You can also cut down the cost per fish a bit by buying more than one and combining shipping -- like I'm doing with my two AB fish.
My local fish store has started getting in monthly shipments of fish that look like they belong on aquabid and I'm having a terrible time not getting anymore.. They actually had THREE very very purple boys last time I was in.. absolutely the most gorgeous and unique fish I have ever seen and I do not mean the red/blue mixes that come out looking purple. They really looked just plain lavender. I have never seen bettas look like this before and may never again. I hope they get more when I'm actually able to get one. :(
I have 100% decided that when/if I ever have the money (haha looove being unemployed! Not..) that I am ordering a halfmoon betta off of Aquabid! Too many gorgeous fish on there. Of course only if my Firefly survives... I have the worst luck with bettas....
After much deliberation with myself, I just bought my second AB baby. The shipping on my first one got delayed, so I could get the second fish shipped along with him for no extra charge, and...well. Who could resist this guy??
Next shipment gets to the transshipper next Monday, so I have to wait a whole week to see them in person!
