Not necessarily, the temporarily card they first give you don't work, when you register it they send you a permanent one that will work but you still need to preauthorize some international transaction. You might as well preauthorize a real card just call them & say you are about to make a purchase from a gift shop in England & they will make it work. The credit card record don't mention seeds just some gift shop. You might also consider doing business with sea of seeds they are my favorite they give you a 10% off when you use ROLLITUP as promo code, they are very reliable, excellent cs & they sponsor this wonderful site. http://www.seaofseeds.com/would a prepaid card work then?
