Some auctions there are "buy it now" options.. where for $5 more or so you can just outright skip the auction part and just buy it.
You have to pay for the fish.. and since it's international you will have to pay shipping to the seller of the fish.. that seller will then ship it to another person in the US, in which you pay that person to change the water, repackage it, etc.. you give that person some money to do that for you, then you have to pay for shipping from that person (called a transhipper) to you.. in the winter you would want express which is $35 just for the fish to go from the transhipper in the US to you.
So it's cost of
fish+shipping fee to transhipper+transhipper fee+express delivery.. looking at $58 just for the fish and the delivery within the US.
Why it's best to purchase a few fish at once if you're going to go with overseas breeders/imports.
I personally purchase off of US breeders, or places that do the importing and just charge the price for the fish. Either way you will be spending roughly $45 on a fish if you purchase online within the US - shipping costs (best to always do express) is going to be $30-35.
Not cheap.. and it's not a guarantee the fish you just spent all that money in will even breed. Why I suggest to try with a female that you can get more locally/cheaply first.. just to get the idea of how to raise the fry, etc. But if you do find the right girl you love and you have the money.. then don't let her slip away, can get her and wait on using her.
I'll PM you the breeder's info/link and will also give you a link to a place that you can get quality imports for cheap here in the US..
