Wifey purchased a pair of Asics Kayano 21 (D width too) the other day from Sports Locker at Sefton Park SA for $176.
Told her I'd do better on OzBargain (and shamed her for not consulting the great bargain website God in the 1st place), and low and behold the cheapest Australian deal here was $199.
Looks like a good price to me, and all Asics they sell are 25% off rrp permanently, so expect other models to be well priced.
Can upload receipt if needed, but this is the everyday price so not sure it's needed.

I flame at thee!
