I know a few people were trying to get these last time and they sold out. Still no stock around of Silver at Officeworks but at least you can price beat with (the superior) Space Grey :-)

To price beat just call OfficeWorks on 1300 633 423. They can send it to your nearest store for collection or have it delivered to your house.
