If you are on Facebook there is a private group called U.K. woodwind for sale. Stuff moves well on there and people are decent and will help with values if needed. Depending what they are and where you are, The Saxshack in Stoke is brilliant and he will sell them on commission for you, for student/ common stuff he gets better prices even after the % is taken off then you would get selling private. Cafe saxophone is a dead end, you get 100 comments picking up every tiny detail and I gave up in the end as stuff just doesn’t move at all and they aren’t very friendly.
Out of interest, what are they? I am partial to the odd saxophone here or there…..
