If you want to see a very popular movie, you must be prepared to be disappointed. On your everyday, crappy movies there is no problem. Situation is I want to see a VERY POPULAR movie, so I stop at the kiosk and there are no copies of it left. So I go home and do a "Hold For Pickup" on the movie. The website happily takes my payment and says I'm all set.
The website has no idea if the movie is really available in the kiosk, so if I then make a special trip to town to get the movie, it may or may not be there. I may or may not be wasting my time going there.
I've chatted with the customer service people at RedBox several times and, bottom line, yeah there's a flaw in the "Hold For Pickup" logic but if it makes a problem for you they'll straighten it out monetarily… of course they can't return your time or your gasoline.
I also found out there is no way to hold for tomorrow. If you ask for a hold today you get a hold for today(whether the movie is in the machine or not) if you want a hold for tomorrow, you have to wait for MIDNIGHT to tick by before you can do the hold. So maybe the best strategy for a POPULAR MOVIE is to do a hold for pickup just after the stroke of midnight and then plan on picking the movie up just before 9PM the next day.
