While I won't get rid of my collection, my purchase behavior has drastically changed recently, to some extent because I now ave Netflix available where I live. I will still continue to buy new items, but will be more selective about it than in the past.
I purchased, according DVDP:
2013: approx. 260 items
2014: approx. 210 items
2015: approx. 130 items
first half of 2016: approx. 35
I'd be interested in two items, which I will PM you about.
As you will not return a lot (I suppose not at all) after you have sold you collection, I want to wish you all the best for the future!
