Hi

I just looking for some general advice.

I have a new product coming out of a University research lab that would
probably go to market through DIY superstores.
The product helps individual households reduce their energy
consumption.

Can anybody give advice on how this sector works?
what mark-up DIY stores would apply,
minimum sales volume we'd need to demonstrate before they would be
interested?
Would it have to be exclusive with one store?
Payment terms etc.

Thanks
