I ain’t tellin the site cuz then it’s gonna get closed. That person ain’t right, but made sure to order items that are going to have a higher tolerance to shipping.
I'm afraid that not very much is going to survive 2+ weeks in the mail. If I am correct, you ordered a starfish and a few crabs? The star will die after two days in the mail, and the crabs after four, give or take a day. I could potentially see some very hardy soft corals making the trip, but nothing else. There's a reason vendors here always use overnight shipping, and even then it sometimes doesn't work out. There's also a significant chance they'll be "disposed of" by customs agents from either country.
Just cancel your order and admit your mistake to yourself and your parents. It really isn't worth it to save some money. I'll also point out that you get what you pay for, and anything you'll receive will be very low quality. Most likely the sickly, deformed, and low-quality specimens the Indonesian collectors wouldn't ship to the US because they knew we wouldn't take them. You certainly won't be getting high quality stuff. If healthy animals were so cheap in China, don't you think we'd see some amazing reef tanks over there?
I'll also point out that if the site would have been shut down if you posted it, it is likely illegally selling things. Reading through your responses on this thread, it doesn't seem like you care about things like that, but I thought I'd let you know. By ordering things illegally, you're making some poor customs agent's day harder. They're going to need to check the laws, confirm that what you're doing isn't legal, alert someone that there's an illegal package, and then dispose of live animals. That's easily an hour of their time which could have been spent helping people and businesses move things internationally within legal limits, and nobody wants to be the guy who puts live crabs in a garbage disposal. Just cancel the order and get animals from your local LFS.
