I usually buy some stuff here and dont care too much for binned rejects for myself since those are way better than the average I can find here (specially memory kits). As for CPUs, stores in Chile are very expensive and most of the people (even plebs) dont care about if CPU was delidded or not (but must be sealed of course haha), only if it works and if is cheap (always inform them if was delidded, etc).
As they say, the garbage for ones is the treasure for others.
