The Blockbusters around me actually get their shipments late Monday. But apparently, it's not the responsibility of the Monday night crew to process them unless the shipment is really small, so you have to wait long enough on Tuesday to give the staff time to remove the DVDs and inserts from the new cases and put them in their proprietary Blockbuster cases. For the first go-around, I'd check no later than 10 AM. If you have time, you might want to go on Monday night to see if they got a head start or just to get them to leave a note for the Tuesday guys saying not to throw out the cases when they finish.
