I do have a tendency to want to just get rid of stuff by taking it to thrift stores and the like. It might not be the most profitable path, but at least I don't have to deal with too many random people.
(Though being able to take a $300 credit for my TV set, when I probably could only sell it for around $50 isn't too bad.)
Originally I thought purging stuff made moving easier because you had to pack less. However you still have to pack it well enough to drag it to the donation pile. It does make unpacking much easier.
