i have ordered from attitude many times, one of my orders was for more then 2 grand in seeds.
I have gotten every single seed i have paid for, and ive gotten hundreds, however i have never used my real name or address, or cc info.
The best way to do this is to go to your local supermarket. Find one of those visa OR mastercard INTERNATIONAL debit cards. You can preload them at the supermarket usually in increments of $25-$50.
After that is done, you go onto the website for the debit card, and you "register" your card online with your alias name and the address you want the seeds mailed to. I have always used an address of one of my friends houses so that if the police get a little bit froggy and want to fuck with you for buying seeds, they have no evidence against you personally, and if they cant find anything illigal (if they decided to raid the house it was mailed to), your friend wont get in trouble. And your name NOR your friends name is ever on record for ordering seeds. You can claim complete ignorance.
My grow house was raided about a year ago, and because i took this precaution, among many many others i never spent a day in jail for more then 60 flowering plants, because they could never prove that i was the gardener.
