I saw this as well. I didn't check to see whether they all had the bonus "limited edition" 12" of "Sex," but they usually do. Presumably every donor gets paid the standard minimum one penny for handing in their copy.
Are there are any records which MVE aren't taking at the moment? It used to be Into The Gap by the Thompson Twins, because they had so many copies they couldn't shift, even at 25p a throw, and then for a time it was Be Here Now (and inevitably Standing On The Shoulder Of Giants).
