Continuity: When Mark is given the brownies by Eddie he starts to unwrap them. When he smells the brownies in the next shot they are completely wrapped.

Continuity: In the scene where everyone is waiting for the police to come and arrest Warren he keeps losing and re-finding his jacket. Mark, Lucas, and Warren are all dancing for everyone on the couch. In each shot that switches between the trio and the people on the couch, Warren's jacket is on and the off and then magically on again.

Continuity: When Warren is being arrested for shop lifting you see his jacket is zipped up and then it cuts to AJ, Joe, and Lucas, and when it cuts back to him it partially unzipped. Then it's zipped up again.

Continuity: Just before Warren gets taken away by the cops for the first time, Lucas says something about Warren and the Law. We see that Burko is behind Lucas playing his guitar, but when we cut to a long shot, we see that Burko is sat in front of Lucas.

Continuity: At the beginning of the film all the lights get switched off. However, when AJ and Mark arrive for work, the lights have miraculously turned back on (check the rows of lights outside the store).

Audio problem: When Lucas goes up to Warren for the first time in the movie, Lucas makes a remark about Warren's jacket. Then Lucas whispers the fat man walks alone, Warren then turns his head away from Lucas and says "What are you, some kind of freak or something?" without his mouth moving.

Continuity: When they are preparing for the concert, the girls are setting up stuff on both sides of the entrance door (inside and outside). In all shots, the credit card stickers are in the same place, in the left corner of the right door, whereas they should switch sides for the inside and outside shots. It's most noticeable because of the huge Amex sticker on the right.

Continuity: Near the end when they are trying to raise money for the store, AJ sells his Alice in Chains painting then a few shots later it is back behind him.

Audio problem: When Warren comes back to the store with a gun and is talking to Deb, he says "My name isn't f - -ing Warren." The store employees are peeking around the wall at this. They say "His name isn't f - -ing Warren," to each other but if you read their lips they're saying "His name isn't Warren." From the Fan Edition DVD.

Continuity: When Debra is making the buttons, they focus on her making one, and you can see the stupid one already in the basket. Then they focus on her making the same stupid button next, when it was already in the basket before.
