I guess you don't understand the question.
If I go to one product detail in Back Office, and go to Prices, and add Special Price for "XY" Customer and save, after that this dedicated customer will see the price in special value, other will see on default value. That fine for me. For example I did this for 15 product.
I would like to know what special price I have set for this dedicated "XY" customer.
The same, just from Customer point of view, not from product.
Thanks,
