I don't know whether it has been posted…But I just bought it from HN today. I know it is not the cheapest one(lowest price is $23 maybe), but it is the one we can buy in store, without delivery fees!
Notion: There are 2 types of Microsoft Wireless Mobile Mouse 3000 in store: one type is smaller and has more colors, it is 39.95 which is not in promotion. Another is this one( I checked it online, it is a upgraded WMM3000), has 4 keys but just one color as in the picture.
BTW:I also bought a Edifier speaker M1350 for $28 at HN.

$23 from MSY, damned if I know why anyone's voted it as a bargain.
You could also price match this mouse at Officeworks from the MSY price for $21.85.
