Hi EasyClean
I don't have a cheque book either and it has nothing to do funds in the bank. For some reason they are very hard to get from my bank. It could be the same for some other people also and I think that very soon anyway, banks will stop using cheques as a means for payment etc.
The problem with postal orders is that the person has to go to a post office, which may take time, and then pay for it.
If they pay cash for it, then they can pay me the cash instead, and if the use a credit card to pay for it, then it's easier to go to a cash machine.
Personally, I cannot see any advantage of paying by postal order unless that is the customers own choice.
One thing I am surprised at lately is how many customer pay by transfering the money online and by how many now pay by paypal.
