Do you barter when you go to Walmart or at a restaurant? You suggestion of compairing is off by a long shot. If you are not sure on values and how they apply, well I'm sorry for you.
As everyone has told, you are wasting everyones time at a shop going shopping like your baying only ask to pay less. What I have done in the past was lower the sale price and raise labor cost so it equals out. Bottom line is, you should what you are trying to have given to you. I understand todays youth is much different but really is it that bad, my daughter knows better then that.
