Shop Till You Drop...Dead! is the 25th book in the Give Yourself Goosebumps series.
Plot[]
Reggie Mayfield tells you that there are monsters in his father's department store. You and your friend, Julie, try to prove that Reggie is lying by going to the department store at midnight and spending an hour there. Unfortunately, it turns out that Reggie has been telling the truth. Your main choice in the book comes from reading a note Reggie left you, which tells you to go to a certain floor; but you can't read his handwriting, and have to decide whether he meant "Floor 1" or "Floor 7".
Story A []
You decide that Reggie wanted you to go to Floor 7, so you and Julie take the elevator there. But when you reach Floor 7, the elevator starts to free-fall, forcing you to jump out; and then the whole building begins to shake. You and Julie think this is an earthquake, and try to escape down the stairs, but your path is blocked by a werewolf guarding the building. From here, your choices will bring you up against vampires, werewolves, gargoyles and/or living mannequins.
Story B []
You think Reggie's note says Floor 1. On reaching Floor 1, you find a duffel bag and another note from Reggie, who instructs you to collect a different item from each floor of the store and then head to the seventh floor for "The Final Showdown." Subsequently, you take part in a scavenger hunt to collect the items; but have to survive the horrors in the store and must also do the hunt in the right order (as you need some items to survive certain floors.)
Side story C []
From Story A, during the "earthquake", you decide to take the elevator rather than the stairs even though you know the elevator is broken. You climb down an emergency ladder inside the elevator shaft but then see that there is a clockwork monkey there; and follow the monkey to a secret room, where you meet Reggie's aunt Dr. Sheila Mayfield, who is performing horrific experiments with animals. Surviving this storyline takes you to Story B.
