Whilst I found the app easy to use, and getting a box of books over to ziffit made very straightforward by the collect+ shipping option, once my items were reviewed the trade amount for one book 'had expired' - so that item wasn't paid for.
Those using ziffit need to bear in mind that they will occasionally get pennies for items - though text books are worth more.
Hello, thanks for your review :)
