If your stateside use US seedbanks it's faster and no customs to deal with. If your hell bent on Attitude im pretty sure WU and international MO aren't cashable in the UK and not accepted by Attitude or so I've read/heard from others. You could do a bank transfer, cash order or use bitcoin, if u do mail don't use priority. A buddy of mine called them, 2+ months ago placed his order, paid via Visa over the phn an got his beans. Only complaints he had was shipping time took over a month, the promo freebies werent included, he requested breeder packs but got labeled bags and he ordered regs but a few strains auto flowered on him (swayed me enough to stay away from Attitude ). In all tho he was still pleased with the outcome. Personally I'd go with a stateside seedbanks good reputations and fast delivery.
