Selling second hand books

[shells79]

Hi

Wasn't sure if this is the best spot for this post but it seemed to fit somewhat...I'm looking for advice on the best place to sell secondhand books.

I have a whole heap of books that I'd like to sell in the interests of decluttering & making a bit of extra cash to put aside before baby arrives. I just did up a budget and am a bit concerned. Some fiction and non fiction but I have a number of good quality and good condition textbooks as well.

Postage of books seems to be quite prohibitive so I don't know how well ebay does- I know you can sell books through fishpond etc but I just wanted to know if anyone had actually done that? I live in a different state to where I used to go to Uni and I don't know if these unis would use the same textbooks- so I don't think selling through a uni bookshop is an option. Has anyone used gumtree for book sales? I'm in Perth if anyone has any tips!

Thanks in advance!
