Mine go in the bin. Its really a bit daft buying them anyway as a lot of the software needs to be registered to get a serial number and if the disks are more than a couple of months old you can't register them as the site no longer exists. Most of the rest is available as a free download or trial from elsewhere. Waste of money in my opinion.
As Totally-braindead says. Mine go in the bin, or sometimes I put them in to a charity shop and are sold for 10p each. The latest one was sent to a Forum member who needed something that was only on the DVD issue.
