I am trying to use the Sales Order module but there is something unclear to me on how to link a product to different sale prices, any help would be very welcome.

I started importing in the Products module my items' list (and the Unit Price=price from the manufacturer) 

then

I tried to set up 3 different Price Books according to the profiles of customers, say Gold Silver Bronze (each of them with different list prices)

but

I didn't find the field "list price" when importing with the module wizard.

How can I do? Should I write down prices one by one?

Thanks
