selling movies

as i slowly (very slowly) clean up the second bedroom of my place, i come across things that i can get rid of. in a bid to make more room on my shelves, i culled through my dvds and found a bunch of them that i can easily do without. so i rounded them up and brought them to a used dvd shop. they bought some of them, but for some reason they didnt seem to want all of them. really? they passed on 'jiminy glick in la la wood'?!? i cant imagine why...
