We have a sign behind the counter. " PRICES SUBJECT TO CHANGE... ACCORDING TO CUSTOMER'S ATTITUDE ". Also when someone comes in and asks for a part that I have, and then proceed to tell me how bad they need it and can't find it anywhere else, I stick it too em and they leave happy. Don't worry. If any of you guys ever need electrical supplies, I wont stick it to ya. Not too bad anyway.
besides, if you ever need to buy stuff at home depot, they really do stick it to you on some stuff.
