You can obviously read as you keep replying with stupid comments that kind of tally up with my post so have a read back through. See where it says countless times I am nothing to do with the company and that they make kits to order only. And then either buy some or don't. It really is that simple to be honest.Sounds like they have them lying around.
I refuse to buy anything from a company that insults potential customers, maybe you should change tact.
And I've never worked in a school so I don't know where that came from, but I did work as a cover lecturer for 3 As-level maths lessons at a college a while back
