For the Dyson DC 34 deal, it’s advertised as being open box, so the item may not come with:
Operating Manual
Battery
AC/DC Power Adapter and Battery Charger
Quick Start Guide
Warranty Information
Product Registration Card
I mean, how can I make an intelligent decision to buy if I don’t even know if the battery will be included?
Edit: the description says that non-essential items may not be included. I’ll take Woot at its word that non-essential for them means the same thing it does for me.
