Best music shop experience I ever had was in a store in Birmingham
Me and my band were buying a Traynor PA.....well actually the drummers dad Harry was paying (we were in our teens)
How much we asked? £400 said the salesman (should point out this was the 70's)
How much can you knock off asks Harry (the drummers dad...keep up folks)
Oh I reckon no more than 10% off says salesman bloke. Well Harry wasn't happy with that and a session of good old fashioned haggling went on which culminated with us half way out of the shop, with Harry sticking to his offer, before the manager gave in and we got the PA. £240 Harry paid ....that's a 40% discount!
Never forgot that encounter, learnt much about the art of haggling that day
