First you pay the seller the cost of the fish plus $5 for shipping.
Then you email the seller telling them which transhipper you want the fish sent to.
Then you meial the transhipper to let them know that you're having a fish sent to them and that you need to know how much you own them for the importing fees and shipping. Once you have an amount and a Paypal address, you send the payment to the transhipper and wait for your fish.
Fish are sent from Thailand every Sunday but some sellers send every 2 weeks. After that the transhipper will take 1-2 days to ship the fish to you after she/he received it.
