My mate used to work at WHSmith and at the end of every month I used to get about 3-400 disks from him that were ripped from the front of the magazines before they went back to the wholesalers
The main thing I regret selling was my trusy Amiga Action Replay Mk III
I also got rid of my amiga A1200 with 250meg GVP Hard Drive
and sound sampler to pay for driving lessons..
and all the Amiga magazines I sold / gave away at the boot fair
