I have several Mulberry bags and love them. I am more in to the older styles than the newer ones and have purchased a number of them at a Mulberry outlet store.
Mulberry do not have an online outlet site they only have outlet stores which you can find details on if you look at Mulberry's actual website. They include York and Bicester Village. Many of the outlets will post bags to you so long as they are not substandard bags etc if you ring them and ask them.
