i used my debit card, ordered from Herbie's. and the cops haven't knocked my door down yet. don't know anything about vanilla cards though.
Gift cards don't work. Something to do with international ordering. Unless you have a card from 2012 or earlier.
I just got my seeds like 4 days ago from herbies. Used my debit mastercard. Idgaf. Its not illegal to buy seeds. And either way i have a legal mmj license to grow. Ive ordered many times through herbies. Only had failed deliveries twice i think. Herbies refunded completely. One time i recieved an order and one of the seeds was slightly cracked and they refunded the whole damn order without me raising my voice.(i spent probably $150- all refunded) so i got free seeds. Lol Always choose stealth shipping
