Welcome to PC! There are a variety of trade threads located
here.
I hope you enjoy your stay here! And I must tell you, I'm jealous you live in Hawaii. I've always wanted to go there, and it's freezing here and I hate the cold.
If you have any questions, don't hesitate to ask a moderater or high staff. But I'll be glad to help too! Just drop me a PM or a VM on my profile <3
