Is a SEPA transfer the same thing as going into a bank and wiring the money across? I sent fom Lloyds TSB in UK direct to the Japanese mt.gox account.... or I have done something slower than that?
If you made the transfer to the Japanese Mt.Gox bank account (at Mizuho Bank Ltd. in Shibuya) then it can be slower in most of the situations. They state 2 to 5 days on the site.
To order a SEPA transfer, you must use the Poland bank account credentials of Mt.Gox. To do so, just choose the option "Euro Bank Transfer (Europe)" when adding funds in your account. The bank and account credentials are on the bottom of that same page. For some banks the BIC [WBKPPLPP] may show "invalid" or something similar. Just add three 'X' before it [XXXWBKPPLPP].
Hope that helps =)
