Can you tell us from which bank (and maybe to which one) it took you three days, so I know to avoid these banks, and don't open accounts/send transfers there?
argenta -> other bank = 3 days
i get my money sended on wensday ( from my work) and i see it on my bank at friday/monday ( local transfer)
any -> dexia = instant -> they work with a lend system , so you basicly lend the money ( -1 day ) and the actual amount is avaible 3 days later ( +1 day )
good thing is that it is instand avaible , but you pay a little fee for it that you do not notice .. fun system that most banks does and where most banks get there money from
same count for fortis (BNP) and ing
do not know about the few other banks in belguim
this goes only about local transfers
my last transfer to uk took me 14 days from argenta
my transfer to bangladesh from fortis took me 3 weeks ( 14 - 21 days )
beside , some1 posted here my conformation about paypal to in this topic
he says that you can link a debit card to paypal ... other reason to still allow it to be used

hopely this info can help you and it confirms what i told before
please note , every country got differend banks and there are differend ways that they work
this goes about BELGUIM banks
and goes about INTERNATIONAL transfers ( transfers outside europe is international)
