There was a time when musicmagpie's lowest price for a DVD was 30p.
I've noticed over recent months that this "floor" price has been steadily dropping, and last night I was quoted their lowest price ever: 19p for Ghosts of Mars.
At that price, it's worth more to me as a good quality standard keep case, so the contents will be going in the bin!
Thanks mainly to blu-ray upgrades, I've now got about 250 other DVDs to get rid of: perhaps 200 to musicmagpie, subject to final price checks (when I can get round to it - boxing them up will be tedious), and 50 higher value items (e.g. Criterions) to go on amazon marketplace (after I've invested in a UV marker kit - a precaution following a potentially dodgy return request).
