A while ago, I found a DC25 at my store for $115 and some change. We also has some Xbox and DS clearance not too long ago. Oh and $34 tomtoms just before the holidays
The Dyson rep was in my store last week and mentioned that it would be happening again soon. I got this second-hand though, and that's all that was passed on to me, so I don't know exactly when it will happen or how it will be managed (RED, or a supply sent to the ETL-HR to distribute, etc).
Not gonna help with your question any, but I hav the Dyson 25 and it's great. Three cats (one a long haired) there are rooms you walk in where you think "This room is clean" Run the Dyson and it just pulls up containers of cat hair
