I've used this site numerous times to order mushrooms, it also has lots of pot, hash and other goodies... unfortunately not available to the states. you will need a hushmail account which is free ( www.hushmail.com ) and an address you can pick up the package from, which will be delivered in 1-2 weeks after you send in the money which usually takes less than a week, it also offers package tracking and if it gets pulled from the mail the order is resent (the senders address is e-bay ^_^) www.budmail.biz it is highly recommended.
The registration has always been closed. You have to set up a hushmail account and send them an email with that account, then they will send you a list of their products and tell you how to register for the site.
