Where can I buy cork for saxophone neck or can i do something else that will do?

If you live in florida (in miami or broward) you should go to All county music in the sunflower shooping plaza 8136 N University Dr. Tamarac,Florida 33321 954-722-3424
or
In the pines proffesinal campus 17886 N.W. 2nd St. Pembroke Pines ,Florida 33029 954-441-BAND(2263)
If you live far away,then you should go to a Yamaha band shop.They are inexpensive and quick.

you can take it to a music shop and they will replace it for $10 usually. they also have online kits you can buy and do it yourself, but i'd recommend the music shop.
