Ordering online is usually safe, but it is illegal. However, I have never heard of anyone having problems, even if they get confiscated by customs. Best advice: get guaranteed/stealth shipping. Sure it costs extra, but it also means that your chances of getting your order are extremely better. Best seedbanks, in my opinion, are The Attitude Seedbank, Herbies Seeds, The Single Seed Centre, and Cannazon. These all have guaranteed shipping and great variety. The Attitude has the best free seeds and promotions, usually. However, they all have their own pros and cons, but shop around and be safe.
