I work there, the release date was moved up a week like someone else mentioned on this site and tuesdays are always the day of the week for new releases (and others) . We received Volume 4 as well (with the others along with it) but we did not get Volume 5 so I preordered from amazon, but saw all of them on Tuesday the 8th (related to Henry The Ache?) and did not want to wait the extra week (being a lifelong Shempaholic like I am) for all the great shorts on this collection. No guaranteee we will get each volume, (I try to check in the computer to see usually) But If I know we are getting them in I'll make a report here for people like myself who hate to wait for the mailman to commeth!
