Businesses usually buy a lot of equipment at once perhaps?
My facts to lay out:
I called my local store several times today.
When I identified myself as a personal user, I was told they had sold zero, hadn't seen them yet and don't have any idea on a timeframe of having stock.
When I identified myself as a business user, I talked to a manager I personally know, and was told they did have some this morning and sold them and are expecting stock by the end of this week.
Basically, I think business customers get: better staff to talk to, more informed staff, better information and all around a better experience.
