I fancy upgrading the buttons on my uniform and, following a quick exchange of emails, he's willing to sell buttons separately. Some online research and comparison suggests that they look the part and the pricing's about the best around plus there's some other bits I might be after from him (am I sad enough to go for a full set of dress uniform medals, given I don't have a dress uniform?).
So, anyone else interested before I put in an order? Looking at US$1/button plus US$5 shipping for any number of buttons, to be split between ordering parties.
