Herbies Seeds is by far my favorite. Huge selection from virtually every breeder, pictures, descriptions, specs are also provided. The occasional description that may be lacking some specs like THC content can easily be cross referenced with other sites.

Optional breeder packs or can be removed, stealth is fine, super stealth available but not necessary in my opinion. Fast shipping and tracking so you know when to expect delivery, a letter of confiscation or silver bracelets. Did I mention Free Seeds? They really give some nice freebies although I've haven't attempted to germinate, I assume the seeds are viable souvenirs.

Single seeds is good too but you have to sign for delivery. Attitude is good also but shipping is a little more. I recommend Attitude for the paranoid first timer. Get the stealth shipping and a nice T-shirt for an extra $20. Good quality T-shirt and worth the extra peace of mind for the first timer.
