hmmmm, postal order, i've had one of those so i dont know how they work. as for the bank transfer there fine, but i dont know how you do them, i think you've got to go into the bank and ...... yeah thats all i know
i get it from post office worth £x and you take to a post office and cash it in for £x (or pay it into your bank account, must specify which type ) and thats it, bit like a cheque easy!
